SendGrid delivers transactional and marketing email. SuprSend decides what is sent, on which channel and when, and sends the email through SendGrid. Most teams use both.
Trusted infrastructure layer behind hundreds of platforms
Twilio SendGrid is an email delivery service, and SuprSend sends email through it. SendGrid gives developers an email API and gives marketers a campaign editor for email. SuprSend is the notification infrastructure above it, where engineering, product and growth run transactional, product and engagement messages on nine channels.
SendGrid delivers the email. The SuprSend workflow decides whether a message should go, on which channel, when, and to whom, then hands the email step to SendGrid and moves to a backup provider if SendGrid does not confirm delivery. The right message reaches the right user at the right time on the right channel, with none of that logic in your application code.
One send step covers email, SMS, WhatsApp, mobile push, web push, the in-app inbox, Slack, Teams and webhooks. Adding a channel is a step in the workflow, on the same user record and log. SendGrid sends email only; SMS, push and chat need other products and your own code.
SuprSend unifies transactional, product and customer engagement messages in one system. A password reset, a comment notification and a win-back campaign share the same users, preferences and logs. SendGrid splits email in two: the Email API and Marketing Campaigns are separate plans with separate send counts.
Each tenant carries its own branding, template version, channel defaults, inbox feed and email provider, with sub-tenants nesting five levels deep. SendGrid’s nearest object is the subuser on Pro: its own credentials, stats and IPs, with templates kept per subuser, not inherited from the parent.
Per category, a user picks channels and a digest schedule, a tenant admin sets the defaults above them, and every send checks those choices first. A hosted page and embeddable components ship with it. SendGrid has unsubscribe groups for email, one group per send.
Ten comments become one digest email. A message waits for morning in the user’s timezone. If SendGrid does not confirm delivery, the workflow sends through a backup email provider. SendGrid sends each request as it arrives, or at a timestamp up to 72 hours ahead.
Each message keeps its workflow run, rendered content, SendGrid’s error and the reason a send was blocked, searchable by user for 30 to 90 days. SendGrid’s activity search keeps 3 days on Essentials and 7 on Pro, with longer history as a paid add-on.
On its own, SendGrid covers email end to end: its own mail transfer agent, domain authentication, dedicated IPs with automated warm-up, address validation, bounce and block classification, an event webhook, inbound parse, and Marketing Campaigns with segments, A/B tests and automations. It does not send on any other channel, hold a preference beyond unsubscribe groups, or wait, batch or branch across a user’s messages.
A product manager changes a workflow in the dashboard. A developer commits the same workflow as a file and ships it through a pull request. A marketer asks Claude to build a list and send a campaign. All three are working on the same workflows, templates and logs, so nobody waits on a ticket.
The built-in agent builds, edits and debugs notifications from a description; product and growth ship without a ticket.
Connect the MCP to Claude, ChatGPT or any client and operate templates, workflows, tenants and preferences from there.
CLI and API keep workflows versioned, diffable and reviewed in pull requests; coding agents make bulk changes.
One SuprSend customer runs its marketing email end to end from Claude Code, with nobody in the dashboard.
SendGrid is built from two places. Developers send through the v3 Mail Send API or SMTP with official libraries in seven languages, and manage dynamic templates and their versions through the API. Marketers build Single Sends and automations in the Marketing Campaigns editor. Twilio’s MCP server, in public beta, lets a coding agent search SendGrid’s docs and API reference; it does not send email or change the account.

SendGridTwilio SendGrid is an email delivery service sold as two products on one account. The Email API accepts mail from your code over REST or SMTP and delivers it from SendGrid’s own servers, with domain authentication, dedicated IPs, suppression lists and an event webhook. Marketing Campaigns adds contacts, segments, a design editor, A/B tests and automations.
SendGrid is one of the email providers SuprSend sends through. What surrounds each email is yours to build: whether and when to send, which user it belongs to, every other channel, and the preferences behind it. The two SendGrid products are bought on separate plans and count their sends separately.
SuprSendSuprSend is notification infrastructure for products where more than one team works on notifications. An event or an API call starts a workflow, and the workflow decides the channel, the timing, the content and the recipients. Engineers integrate once; product and growth build and change workflows, templates, lists and broadcasts from the dashboard or through an agent.
SuprSend runs no mail server. It sends each email step through your SendGrid account with your API key, reads SendGrid’s event webhook for delivery and engagement, and can fall back to a second email provider. Push, SMS, WhatsApp, an in-app inbox, Slack and Teams run through the same workflows, preferences and logs.
SendGridEngineers write the send logic against the v3 Mail Send API or SMTP, keep the templates, and process the event webhook in their own code. Marketers build Single Sends, segments, signup forms and automated series in Marketing Campaigns, on a plan bought separately from the Email API.
Agents connect to Twilio’s MCP server from Claude Code, Cursor or Codex and search SendGrid’s docs and API reference while writing the integration.
SuprSendEngineers integrate once through the API, a backend SDK in Python, Node, Java or Go, the CLI and MCP, and keep workflows and templates in the repo. Product and growth build workflows, lists, content and broadcasts in the dashboard, or have the built-in agent build them, with versions to roll back and a test mode.
Agents connect over MCP from Claude, ChatGPT, Claude Code or Cursor and create users, set preferences, write templates, trigger a notification, run a broadcast and read the delivery log.
From both products, documentation sites and pricing pages, September 2026. Plan names mark the lowest plan that includes a feature.
In SuprSend a notification is a workflow and a set of templates, each with an API and a file form behind the dashboard, so it can be edited by a person, scripted, versioned and staged. In SendGrid a transactional email is a request your server builds against a stored template, and a campaign is a Single Send or an automation in the Marketing Campaigns editor.

SuprSend is worked in by engineers, product and growth, with separate environments and a test mode between them and real users. SendGrid splits by product: engineers own everything sent through the Email API, and marketers own what goes out of Marketing Campaigns, on its own plan.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Who builds send logic | Engineers, product and growth, in the dashboard, by CLI or through an agent | Engineers, in server code |
| Who sends campaigns | Product, growth and marketing, from the dashboard, the API or an agent | Marketers, in Marketing Campaigns |
| Transactional notifications | YESEvery channel | YES, BUTEmail only, through the Email API |
| Customer engagement campaigns | YESEvery plan, every channel | YES, BUTEmail only, on a Marketing Campaigns plan |
| One system across both | YESSame workflows, preferences and logs | PARTIALOne account and one domain setup; separate plans and send counts |

| Test mode that blocks real delivery | YESIn development and staging | PARTIALSandbox mode validates one request without delivering it |
| Team members | Unlimited on every plan | 1 teammate on the trial and Essentials; 1,000 on Pro |
| Roles and permissions | YES, BUTRBAC on Enterprise | YESTeammate permissions and API key scopes |
SuprSend starts from a user: one profile holds every channel address, every device and any properties, and tenants sit above users. The SendGrid Email API starts from an email address in the request. Marketing Campaigns keeps contacts with typed fields, and the subuser is its unit for separating customers.
| Capability | SuprSend | SendGrid |
|---|---|---|
| User profile | YESOne user, every channel address, any JSON properties | PARTIALMarketing Campaigns contacts; the Email API sends to addresses |
| Custom properties | Any number per user, any JSON value, no schema to declare | Custom fields typed as text, number or date, created before use |
| How contacts arrive | SDK, API, CSV, warehouse SQL, Segment, Mixpanel, Amplitude | CSV, the console, signup forms, the Contacts API |
| Non-user recipients | YES, BUTObjects with their own channels and subscribers; Business | NO |
| Tenants | YES, BUTNested five levels; Business add-on, Enterprise | PARTIALSubusers on Pro, one level, with own credentials, stats and IPs |
| Per-tenant templates and branding | YES, BUTOne template with tenant variants; Business add-on, Enterprise | PARTIALEach subuser keeps its own templates; the parent’s are not visible to it |
| Per-tenant sending domain and provider | YES, BUTBusiness add-on, Enterprise | YES, BUTAuthenticated domains assigned to subusers; Pro |
| Per-tenant preference defaults | YES, BUTBusiness add-on, Enterprise | NO |
Both send campaigns from a dashboard. Marketing Campaigns sends email to segments of contacts, with forms, A/B tests and automated series. SuprSend broadcasts to a list on any channel through the workflow engine. A marketing team working in the SuprSend dashboard also runs the event-driven transactional messages, such as password resets, invoices and alerts, from the same workflows, lists and logs as its campaigns.
| Capability | SuprSend | SendGrid |
|---|---|---|
| How an audience is built | Segmentation rules, scheduled warehouse SQL, CSV, API, Segment, Mixpanel, Amplitude | Lists and segments on contact fields and engagement |
| Audience refreshes on its own | YES, BUTDynamic lists: add-on on Essentials and Business, Enterprise | YESSegments update as contacts change |
| Campaign channels | All nine, one or several per send | |
| Scheduling | One-time, scheduled, recurring; recipient’s timezone from Essentials | Send now or schedule a Single Send |
| Campaign runs through a workflow | YESCan batch, route across channels and respect preferences | NOA Single Send is one email to a list or segment |
| Automated series | YESWorkflows with delays and branches on every channel | YES, BUTAutomations on Advanced, email only |
| Transactional messages from the same dashboard | YES | NOTransactional email is API calls on a separate plan |

SendGrid is an email service. SuprSend covers nine channels from one workflow and uses SendGrid, or another email provider you choose, for one of them. Push, the in-app inbox, Slack and Teams connect directly with no provider in between.
| Capability | SuprSend | SendGrid |
|---|---|---|
| YESThrough SendGrid, Amazon SES, Mailgun, Postmark, Resend and others | YES | |
| SMS | YESThrough your SMS provider | NOTwilio Programmable Messaging is a separate product |
| YESThrough a provider or the WhatsApp Cloud API | NO | |
| Mobile push | YESDirect to FCM and APNs | NO |
| Web push | YES | NO |
| Slack and MS Teams | YES | NO |
| In-app inbox | YES | NO |
| Webhook as a channel | YES | NO |
| Fallback to another channel | YESSmart channel routing stops once the user engages | NO |
Under SuprSend the email is SendGrid’s in both setups, so deliverability, IPs and authentication stay in your SendGrid account. SendGrid owns the mail servers and the tooling around them. SuprSend adds a second provider to fall back to, and the timing and preference checks before the call.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Mail servers | Your email provider’s | SendGrid’s own mail transfer agent |
| Domain authentication, link branding, reverse DNS | Set up in your provider account | Every plan |
| Dedicated IPs and warm-up | Your provider’s | One IP included on Pro; pools and automated warm-up |
| Fallback to a second email provider | YES, BUTEssentials; moves on when delivery is not confirmed | NOOne provider |
| Scheduled send | YESDelay, schedule, or hold for the user’s timezone | YES, BUTUp to 72 hours ahead through the API |
| Cancel a scheduled send | YESBy run, recipient or workflow | YES, BUTBy batch ID, until 10 minutes before send time |
| Suppression of bounces and spam reports | SendGrid’s suppressions still apply; SuprSend logs the result | Bounces, blocks, spam reports, invalid addresses and unsubscribes |
| Address validation | NO | YES, BUT2,500 checks a month on Pro, 5,000 on Premier |
| Inbound email | NOReplies go to the reply-to address you set | YESInbound Parse webhook |
A workflow is the logic between a trigger and a send: wait, batch, branch, pick a channel, stop. SuprSend has it as a product. SendGrid sends each API request as it arrives or at a set time, and its automations are email series for marketing contacts, so the rows below are mostly code you write and host.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Multi-step workflows | YES | PARTIALAutomations send an email series; Advanced |
| Delay and wait for an event | YES | PARTIALDelays between automation emails; no wait on a product event |
| Batching and digest | YES, BUTBusiness | NO |
| Branches and conditions | YESEvery plan | NO |
| Send in the recipient’s timezone | YES, BUTEssentials | PARTIALsend_each_at takes a timestamp per recipient that you compute |
| Throttle per user | YES, BUTEssentials | NO |
| Fetch from an API, call a webhook | YES, BUTEssentials | NO |
Both store email templates outside your code with Handlebars variables and versions. SuprSend adds editors for the other eight channels, translation files and tenant variants. SendGrid’s templates cover email only, and a copy change to a Marketing Campaigns send is a separate design.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Editor per channel | YESAll nine channels | PARTIALDesign and code editors for email |
| Variables and conditional content | YESHandlebars | YESHandlebars in dynamic templates |
| Translations | YES, BUTIn the template on Essentials; translation files on Business | NOA template per language, or conditions in Handlebars |
| Version history and rollback | YES | YES, BUT300 versions across all templates per account |
| Variants by tenant | YES, BUTMulti-tenant add-on, Enterprise | PARTIALA copy of the template in each subuser |
| Test send with sample data | YES | YESTest data and test email from the editor |
| Inbox and spam testing | NO | YES, BUTEmail content testing credits; 60 a month on Pro |
A preference is a user’s standing choice about what they hear and where. SuprSend stores it per category and channel and checks it before every send. SendGrid has unsubscribe groups: each email names one group, and a recipient can leave that group or unsubscribe from everything.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Preferences per category | YES, BUTBusiness | PARTIALUnsubscribe groups, one group per send |
| Preferences per channel | YES, BUTBusiness | NOOne channel |
| Digest schedule chosen by the user | YES, BUTBusiness | NO |
| Tenant admin defaults above the user | YES, BUTMulti-tenant add-on, Enterprise | NO |
| Hosted page and embeddable components | YES, BUTBusiness | YES, BUTManage Preferences page, up to 25 groups shown |
| Opt-out checked on every send | YESBlocked sends are logged and not billed | YESMail to suppressed addresses is dropped |
SendGrid has no in-app channel. SuprSend’s inbox is a persistent feed inside your product, with read state, fed by the same workflow that sends the email, so a message can land in the inbox first and go out by email only if it is not seen.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Persistent feed with read state | YESEvery plan; SuprSend branding on Free | NO |
| Drop-in components | YESReact, Angular, Vue and JavaScript | NO |
| Headless and mobile SDKs | YESHeadless on React Native, Flutter and iOS; native Android SDK | NO |
| Tabs, filters, pin, snooze and archive | YES | NO |
| Toasts | YES | NO |
| Email only when the inbox message is unseen | YESSmart channel routing | NO |
SuprSend answers the question about one user across every channel: what was sent, what it said, and why it did not arrive. SendGrid answers the question about email in depth, with bounce classes and mailbox-provider reporting, and streams events to your endpoint.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Per-message log | YESSearchable by user, workflow, tenant and status | YES, BUTEmail activity, searchable for 3 days on Essentials and 7 on Pro |
| Rendered content and provider error | YES | PARTIALBounce and block reasons with a classification |
| Reason a send was blocked | YESOpt-out, missing channel, failed condition | PARTIALSuppression reason when a message is dropped |
| One log across channels | YES | NOEmail only |
| Retention | 30 days Free, 90 days paid | 3 or 7 days searchable; longer history for purchase |
| Streaming and export | Warehouse sync on Business; Datadog, New Relic on Enterprise | Event webhook: 1 on the trial, 2 on Essentials, 5 on Pro |
| Deliverability reporting | Delivered, seen, clicked and failed per workflow, template and tenant | Deliverability insights, ISP feedback loop data, mailbox provider stats |
Both are API-first. SendGrid’s strength is the send path itself: SMTP for any stack and libraries in seven languages. SuprSend’s is everything around the send being an asset you can pull into the repo, type-check and promote.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Backend SDKs | Python, Node, Java, Go | C#, Go, Java, Node.js, PHP, Python, Ruby |
| Frontend SDKs | JavaScript, React, React Native, Flutter, iOS, Android | None; email has no client side |
| REST API | YES | YESv3 |

Twilio’s MCP server and skills help a coding agent write a SendGrid integration. SuprSend’s agents build and run the notifications themselves.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Build a workflow from a description | YESSuprSend agent, in the dashboard or Slack | NO |

SendGrid carries Twilio’s certifications and offers EU data residency, and it is not a HIPAA-eligible service. SuprSend signs a HIPAA BAA on Enterprise and offers a choice of where it runs.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Two-factor sign-in | On every plan | Required for every user |
| Single sign-on | Google and GitHub on every plan; SAML on Enterprise | SAML SSO on Pro and Premier |

SendGrid bills per email sent, counting a message whether it lands, defers or goes to spam, and bills the Email API and Marketing Campaigns separately. SuprSend bills per notification per channel, counts a digest as one, and does not bill sends blocked by an opt-out. With both, you pay each vendor, and SendGrid still delivers the email.
50,000 emails in a month cost $19.95 on SendGrid Essentials. Sent through SuprSend, the same 50,000 add $100 on SuprSend Essentials, billed annually, for $119.95 across two bills. The SuprSend line buys the workflow, preferences, failover and every other channel; the cost on the SendGrid-only side is the engineering time for that logic. Compare on your own event-to-notification ratio; SuprSend’s pricing page has the detail.
| Capability | SuprSend | SendGrid |
|---|---|---|
| Billing unit | Notification per user per channel; digest counts as one | Email per recipient; Email API and Marketing Campaigns counted separately |
| Free | 10,000 notifications a month; all channels; unlimited members | 60-day trial at 100 emails a day |
| Entry paid | Essentials $100 per month billed annually; 50,000; $2 per extra 1,000 | Essentials from $19.95 per month; 50,000; $0.0013 per extra email |
| Next tier | Business $250 per month; adds digest, preferences, objects | Pro from $89.95 per month; 100,000; dedicated IP, subusers, SSO |
| Enterprise | Custom; volume discounts; monthly-tracked-user option | Premier, custom pricing |
| Other costs | Your email, SMS and WhatsApp providers | Marketing Campaigns from $15 per month; extra IPs, activity history and testing credits |
| Time to first notification | Same day; SendGrid API key added as the email vendor | Same day for a first send; the logic around it follows |
Nothing leaves SendGrid. Your account, authenticated domains, IPs and suppression lists stay where they are, and SuprSend becomes the caller. Email keeps going out through SendGrid throughout, so the move can go one notification at a time.
| SendGrid | SuprSend | Moves how |
|---|---|---|
| SendGrid account and API key | Email vendor | Add the API key; account stays |
| Authenticated domain and IPs | Stay in SendGrid | No change |
| Event webhook | Delivery status in SuprSend logs | Point a webhook at SuprSend’s endpoint |
| Dynamic template | Email template with versions | Export HTML; Handlebars variables carry across |
| Mail Send call in server code | Workflow trigger | One event or API call per product action |
| Addresses in your database | User profile | Users API or backend SDK |
| Unsubscribe group | Preference category | Recreate; import opt-outs by API |
| Subuser | Tenant | Create the tenant; route to that subuser’s key |
| Contact list or segment | List | CSV, API or CDP sync |
| Single Send | Broadcast to a list | Rebuild; or keep Marketing Campaigns for A/B tests |
| Suppression lists | Stay in SendGrid | SendGrid still drops suppressed addresses |
| Email activity | Stays; SuprSend logs sit beside it | No change |
Inventory every place your code calls SendGrid to send, every dynamic template, and every unsubscribe group.
Set up SuprSend development and staging, and add your SendGrid API key as the email vendor, with a second provider for fallback if you want one.
Point a SendGrid event webhook at SuprSend, import users with their email addresses, and move templates by exporting their HTML.
Rebuild the critical notifications as workflows first: password resets, receipts, security alerts. Run them in test mode.
Switch those triggers from the Mail Send call to a SuprSend event, one at a time, and compare the logs for a week.
Move the rest, then add what SendGrid could not do: a second channel, a digest, preferences, the inbox.
Enterprise customers get migration support and a scoped plan; on other plans the Slack community and docs are the path.
No. SendGrid delivers email, and SuprSend sends email through it. The two overlap only where Marketing Campaigns sends campaigns from a dashboard.
The real choice is between writing the logic around SendGrid yourself (timing, retries across providers, other channels, preferences, per-customer content) and using SuprSend for it.
Yes. You add your SendGrid API key as an email vendor in SuprSend and point a SendGrid event webhook at SuprSend. SuprSend sends through your account, so your domains, IPs, suppressions and SendGrid reporting stay yours.
SuprSendSuprSend, with SendGrid delivering, suits a product that also sends push, SMS or in-app messages, needs delays, digests or preferences, or wants product and growth to change notifications themselves.
SendGridSendGrid directly suits a product where email is the only channel, the send logic already lives on your server, and nobody outside engineering needs to change a notification.
No. SuprSend is a second bill on top of SendGrid, which still delivers the email. SendGrid Essentials starts at $19.95 a month; SuprSend has 10,000 notifications a month free and Essentials at $100 a month billed annually for 50,000. The saving is the engineering time you would spend building around SendGrid.
SuprSendSuprSend tenants carry their own branding, template versions, channel defaults, inbox feed and email provider, nest five levels deep and inherit from their parent, as a Business add-on or on Enterprise.
SendGridSendGrid has subusers on Pro: each has its own credentials, stats, IPs and templates, one level deep, and templates made on the parent are not visible to its subusers.
Yes. Marketing Campaigns keeps its lists, forms, A/B tests and automations on its own plan. SuprSend runs the product and transactional notifications, and the two share your SendGrid domain and suppressions. Teams that want campaigns and transactional messages in one place move campaigns to SuprSend broadcasts.
SuprSendSuprSend runs as SuprSend cloud on every plan. On Enterprise it also runs in your VPC, on-prem or as bring-your-own-cloud, with the full product and vendor support; see the self-hosting page.
SendGridSendGrid runs on Twilio SendGrid’s cloud, with an EU data residency option.
