Resend delivers the email. SuprSend decides whether a message goes, on which channel, when and to whom, and hands the email step to Resend. Most teams use both.
Trusted infrastructure layer behind hundreds of platforms
Resend is an email API for developers and one of the providers SuprSend sends email through; Resend’s own guide to notification infrastructure lists SuprSend as the orchestration layer above an email API. Resend is built for engineers who own email end to end. SuprSend is the notification infrastructure where engineering, product and growth run transactional, product and engagement messages on nine channels.
Resend 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 Resend and moves to a backup provider if Resend 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, Slack, Teams, the in-app inbox and webhooks, on one user profile. The workflow tries the inbox, then push, then email, and stops once the user responds. A Resend Automation has one outbound step, Send Email.
SuprSend unifies transactional, product and customer engagement messages in one system. A password reset, a comment notification and a win-back broadcast share the same users, preferences and logs. Resend splits email across its send API, Automations and Broadcasts, with marketing on a separate plan billed per contact.
Each tenant carries its own Resend domain or provider, its own version of every template, admin-set channel defaults and a per-tenant inbox feed, with sub-tenants nesting five levels deep. Resend’s multi-tenant guide gives each customer a verified domain and a scoped API key, or a separate account.
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, transactional or campaign. Resend Topics cover Broadcasts and Automation emails; for transactional email you add the unsubscribe header and store the choice yourself.
Fifty comment events become one digest at the time the user chose. A 2 a.m. alert waits for 9 a.m. local time. If Resend does not confirm delivery, the email step moves to a backup provider such as SES or SendGrid. Resend Automations have delay and wait-for-event steps.
Each message keeps its workflow run, rendered content, Resend’s response and the reason a send was blocked, such as an opt-out or a batch, searchable by user for 30 to 90 days. Resend’s logs show each email it was asked to send and what happened to it afterwards.
On its own, Resend covers the email half well: Automations with condition, delay and wait-for-event steps, Topics for subscriptions, a brandable unsubscribe page, and webhooks for every delivery event. It does not reach a second channel, hold a category preference across channels, batch, wait for a user’s timezone, move to another provider, or keep templates and defaults per customer account.
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.
Resend meets developers and agents well on the email side. React Email templates are uploaded from the repo with its CLI, the hosted MCP server signs in with OAuth, and one-click plugins cover Claude, Claude Code, Cursor and Codex. Its dashboard assistant drafts an email or an automation for a person to finish, spending a monthly AI credit. There, the agent operates the email account; in SuprSend it operates the whole notification, with its channels, preferences and backup provider.

ResendResend is an email API for developers. One account covers transactional sends, marketing Broadcasts, event-triggered Automations and inbound mail, with templates written as React components, official SDKs in nine languages, a CLI and a hosted MCP server.
Resend is one of the email providers SuprSend sends through. What surrounds each email is yours to build: every other channel, preferences that hold across channels, batching, timezone holds, a backup provider, and anything that differs per customer account.
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, timing, content and recipients. Engineers integrate once; product and growth change the rest.
SuprSend delivers no email on its own. It sends the email step through your Resend account with your key and domain, and records what Resend returned. SMS, push, WhatsApp, an in-app inbox, Slack and Teams run through the same workflows, preferences and logs.
ResendEngineers send through the API, SDKs, CLI or SMTP relay, and upload React Email templates from the repo. Marketers and product managers write templates, Broadcasts and email Automations in the dashboard, with AI drafting that spends monthly credits.
Agents connect to the hosted MCP from Claude, Claude Code, Cursor or Codex and operate emails, templates, contacts, broadcasts, automations and logs.
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.
Resend has an API, a CLI and an MCP server behind its dashboard, for email. SuprSend has the same three behind its dashboard for the whole notification: workflows, templates, tenants, lists, categories and translation files, staged and promoted like code.

Resend’s marketing side is Broadcasts to existing contacts, on a Pro Marketing plan billed per contact. SuprSend broadcasts to lists on every plan through the same workflow engine as its transactional messages, so a campaign can batch, route and respect preferences. 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 | Resend |

Two bills. Resend charges for each email it sends or receives, counting every To, CC and BCC address. SuprSend charges for each notification it sends on any channel, counts a digest as one, and does not bill sends blocked by an opt-out. With both, each bills for its own part.
The units measure different things, so the headline prices do not compare. A team sending 40,000 emails and 10,000 in-app notifications a month pays Resend Pro $20 for the email and SuprSend Essentials $100 for the 50,000 notifications, $120 in total; the same 40,000 emails on Resend alone cost $20. Compare on your own event-to-notification ratio; SuprSend’s pricing page and Resend’s have the detail.
| Capability | SuprSend | Resend |
|---|---|---|
| Billing unit | Notification per user per channel; a digest counts as one | Email sent or received; contacts for marketing; runs for Automations |
| Free plan | 10,000 notifications a month on every channel | 3,000 emails a month at 100 a day; 1,000 contacts; 10,000 runs |
| Entry paid plan | Essentials, $100 a month for 50,000, $2 per 1,000 more | Pro, $20 a month for 50,000, $0.90 per 1,000 more |
| Next plan | Business, $250 a month for 50,000, $5 per 1,000 more | Scale, from $90 a month for 100,000 to $1,150 for 2.5 million |

| Add-ons | Multi-tenancy and dynamic lists below Enterprise | Domains $20, dedicated IP $30, SSO $150 a month |
| Annual billing | Essentials and Business billed annually | Enterprise only |
| Time to first send | Resend connected in minutes; first workflow in a day | Domain verified and first email in minutes |
Nothing leaves Resend. Your account, domains, API key and suppression list stay where they are, and SuprSend becomes the caller. Email keeps going out through Resend throughout, so the move can go one notification at a time.
| Resend | SuprSend | Moves how |
|---|---|---|
| API key and verified domain | Email vendor: Resend | Key and sender added in vendor settings |
| Per-customer domains | Tenant vendor settings | One Resend domain or account per tenant |
| Webhook endpoint | Delivery events on each notification | SuprSend’s Resend webhook added, all events |
| Templates | Email templates | HTML pasted in; variables become Handlebars |
| Contacts and properties | Users and properties | Exported, loaded by API, SDK or CSV |
| Segments | Lists | Rebuilt as rule or query lists |
| Topics and unsubscribes | Categories and preferences | Topics become categories; opt-outs imported |
| Automations | Workflows | Rebuilt; event names stay the same |
| Broadcasts | Broadcasts to a list | Rebuilt, on any channel |
| Suppression list | Stays in Resend | Resend keeps suppressing |
Inventory every place your code calls Resend, and every Automation and Broadcast in the Resend dashboard.
Set up SuprSend development and staging, add Resend as the email vendor with a backup provider behind it, and create tenants with their own Resend domains where you have them.
Load users, lists, categories and existing opt-outs.
Rebuild the critical flows first, trigger them in test mode from the same event names, and compare the rendered email with the Resend original.
Switch those triggers to SuprSend one at a time, and compare Resend’s delivered counts with SuprSend’s logs for a week.
Move the rest, retire the direct Resend calls, and keep an export of old Resend events, which age out after 30 days.
Enterprise customers get migration support and a scoped plan; on other plans the Slack community and docs are the path.
No. Resend delivers email, and SuprSend sends its email step through Resend. The two meet only where email is your one channel and the choice is between a Resend Automation and a SuprSend workflow.
The real choice is between writing the code around Resend yourself (other channels, preferences, batching, a backup provider) and using SuprSend for it.
Yes. Resend is a built-in email vendor in SuprSend: you add your API key and sender, verify the domain in Resend, and add SuprSend’s webhook so delivery, open and click events come back. Different tenants can send through different Resend domains or accounts, with a second provider behind Resend.
SuprSendSuprSend, with Resend delivering, suits a product that also sends push, SMS or in-app messages, needs digests, timezone holds or preferences, or wants product and growth to change notifications themselves.
ResendResend directly suits a product where email is the only channel, the send logic already lives in your code, and nobody outside engineering needs to change a notification.
No. For email alone, Resend is the only bill, from $20 a month for 50,000 emails. SuprSend bills per notification per channel, with 10,000 a month free and Essentials at $100 for 50,000, and Resend still bills for the email it delivers. The saving is the engineering time you would spend building around Resend.
SuprSendSuprSend tenants carry their own provider, templates, branding, channel defaults and inbox feed, nest five levels deep, and come as a Business add-on or on Enterprise.
ResendResend gives each customer a verified domain and a domain-scoped API key in one account, or a separate account. In the shared account, customers share one sender reputation and one rate limit, and there are no per-customer analytics.
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.
ResendResend runs in Resend’s cloud. Each domain sends from one of four regions, and account data is stored in the US.
