SuprSend vs SendGrid: notifications above the email API

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.

Send the email through SendGrid and run everything around it

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 workflow reaches every channel

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.

Every kind of message runs from one system

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 customer account is a tenant with its own setup

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.

Users choose channels per category, admins set the defaults

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.

Digests, timezone holds and provider failover in every workflow

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.

Logs that say why a message did not arrive

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.

Build notifications in the dashboard, in your own agent, or in your codebase

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.

What each actually is

SendGrid

Twilio 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.

SuprSend

SuprSend 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.

Where they overlap

Email to your usersBoth send it. Under SuprSend, the delivery is SendGrid’s own.

Templates with HandlebarsSendGrid’s dynamic templates and SuprSend’s email templates both use Handlebars variables, with a drag-and-drop editor and a code editor.

Campaigns from a dashboardMarketing Campaigns sends Single Sends and automations to segments. SuprSend broadcasts send to a list once, on a schedule or on repeat.

Audience buildingSendGrid segments contacts on fields and engagement. SuprSend builds lists from rules, warehouse SQL, CSV, the API or a CDP.

Scheduled sendsSendGrid’s API schedules up to 72 hours ahead, and Marketing Campaigns further. SuprSend delays, schedules and holds a message for the user’s timezone.

Where SendGrid alone is enough

Deliverability tooling at volumePro includes a dedicated IP, with IP pools, automated warm-up, reverse DNS and link branding in the plan.

Address validation before you sendThe Email Address Validation API checks addresses, with 2,500 checks a month included on Pro and 5,000 on Premier.

Inbound emailInbound Parse posts incoming mail and replies to your own endpoint.

Marketing tools built for emailSignup forms, A/B tests of subject and content within a send, and automated series on Marketing Campaigns Advanced, from $60 a month.

EU data residencySendGrid offers an EU data residency option for email data.

Official libraries in seven languagesC#, Go, Java, Node.js, PHP, Python and Ruby, plus SMTP for anything else.

An email-only productOne channel, send logic your server already owns, and one unsubscribe link: an orchestration layer adds a bill and little else yet.

When you need SuprSend on top

One backend call in place of per-email codeYour server sends one event. The template, the recipient’s address, the sender and the SendGrid call are resolved in SuprSend.

More ways to triggerA product event, an API call, a schedule, a broadcast to a list, or a Segment event can each start the same workflow.

Delivery answers per user across channelsSupport looks up one person and sees every email, push and SMS, what SendGrid returned, and whether it was opened.

Duplicate protectionSuprSend accepts an idempotency key, so a repeated request does not send twice.

One template in every languageTranslation files per language render the same template in each locale, pushed and pulled by the CLI with the templates.

Cancel a notification in flightA run can be cancelled by run, recipient or workflow at any point before it sends.

Environments and a test modeDevelopment, staging and production are on every plan, and test mode blocks real delivery while a workflow is being built.

A choice of where it runsSuprSend cloud on every plan; your VPC, on-prem or BYOC on Enterprise, with the full product and vendor support.

Who works in it

SendGrid

Engineers 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.

SuprSend

Engineers 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.

How notifications are built and changed

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.

Capability	SuprSend	SendGrid

Teams and scope

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

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

Data model and tenancy

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

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

Customer engagement and marketing

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

Channels

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
Email	YESThrough SendGrid, Amazon SES, Mailgun, Postmark, Resend and others	YES
SMS	YESThrough your SMS provider	NOTwilio Programmable Messaging is a separate product
WhatsApp	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

Email delivery

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

Workflows

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

Templates and content

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

Preferences

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

In-app inbox

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

Analytics and logs

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

Developer experience

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

Pricing and implementation

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

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

Putting SuprSend on top of SendGrid

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.

FAQ

Is SuprSend a SendGrid competitor?

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.

Can SuprSend use SendGrid?

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.

Should I use SendGrid directly or through SuprSend?

SuprSend

SuprSend, 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.

SendGrid

SendGrid 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.

Is SuprSend cheaper than SendGrid?

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.

Does SendGrid do multi-tenancy?

SuprSend

SuprSend 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.

SendGrid

SendGrid 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.

Can I keep Marketing Campaigns and use SuprSend?

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.

Where does each run, and can I self-host SuprSend?

SuprSend

SuprSend 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.

SendGrid

SendGrid runs on Twilio SendGrid’s cloud, with an EU data residency option.
