**In short.** Resend is a hosted transactional email API with strong developer experience, billed per email sent through Resend's own cloud. SendBunny is a $199 one-time license that installs campaigns, a template editor, automations and a transactional API directly onto your own Amazon SES, so the sending infrastructure and the audience data both live in your AWS account. Resend is the sharper pick for a team that wants zero infrastructure and only ever sends transactional mail; SendBunny is the sharper pick once you also need a campaign UI or want the sending path to be yours.

## A hosted API, or a platform on infrastructure you own

Resend's product is the developer experience of sending an email: a clean SDK, good docs, webhooks that behave, all running on Resend's own cloud. What it does not give you is a home for the audience itself; list management and campaign sending are limited compared to a full email service provider, and every email routes through Resend's infrastructure and Resend's billing.

SendBunny takes the opposite shape. It installs as a CloudFormation stack into your AWS account with one click, and from that point on it sends through your own Amazon SES identity, not a shared vendor cloud. The license is $199 once, unlimited contacts included, and Amazon SES bills you directly for what you send, at roughly $0.10 per 1,000 emails.


## Feature by feature

| Feature | SendBunny | Resend |
| --- | --- | --- |
| Where it runs | Your AWS account | Resend's hosted cloud |
| Pricing model | $199 once, plus SES | Per-email SaaS plan |
| Campaign and list UI | Built in, in your account | Developer-first API focus |
| Cost in a quiet month | About $0 platform cost | Plan floor still applies |

SendBunny's install includes campaigns, a drag-based template editor, automations, a shared team inbox, delivery analytics and a REST [transactional send API](https://sendbunny.co/docs/send-email-api), all reading and writing to the same account. Resend's strength runs the other way: it is purpose-built for developers sending transactional mail from application code, with less surface aimed at marketing campaigns or a shared inbox.


## What it costs as volume grows

|  | 10,000 emails/mo | 50,000 emails/mo | 1,000,000 emails/mo |
| --- | --- | --- | --- |
| SendBunny (Amazon SES) | ~$1 | ~$5 | ~$100 |
| Resend, Pro plan (approx.) | ~$20/mo | ~$20/mo (Pro includes 50k) | ~$650/mo (Scale plan) |

Resend list prices from its pricing page, checked July 2026.

Resend's Pro tier absorbs the first 50,000 emails a month for a flat rate, which is a fine deal at that volume and simpler to budget than raw SES pricing. The gap opens at real scale: a million emails a month runs close to $650 on Resend's Scale plan, against roughly $100 in Amazon SES send fees plus the one-time SendBunny license already paid. The markup on hosted per-email pricing is the price of not touching AWS at all, and it grows with volume rather than shrinking.


## What you give up moving off a hosted API

This is the honest tradeoff, not a footnote. Resend's SDKs, webhook reliability and documentation are built for one job and do it well, and a team that only ever sends transactional email, password resets, receipts, one-off notifications, may never need anything SendBunny adds on top. SendBunny's [send API](https://sendbunny.co/docs/send-email-api) covers the same from, to, subject, body and template-alias pattern, with suppression enforced automatically, but it is one part of a wider platform rather than the entire product.

The other side of that tradeoff is what SES brings back: an AWS account you already pay for, no separate vendor relationship for email, and no per-email markup once volume climbs past what a Pro-tier plan covers.


## Who should stay on Resend

- **Pick Resend if** you send only transactional email, want zero AWS involvement of any kind, and value a purpose-built developer API over a campaign UI.
- **Pick SendBunny if** you already use AWS, want campaigns and transactional sending from the same account, or expect volume to grow past the point where per-email SaaS pricing stays reasonable.

A team just prototyping, sending a handful of transactional emails a month with no AWS account in sight, will get moving faster on Resend's free tier than on a CloudFormation install. That advantage narrows as soon as a marketing list, a template library or real send volume enters the picture.


## Running the two side by side, then cutting over

1. **Keep Resend live** while you install SendBunny with the one-click `Create stack` step in your AWS account, about ten minutes.
2. **Verify your sending domain on Amazon SES**, using the DKIM, SPF and DMARC records the app generates.
3. **Point your application's send calls at the SendBunny API** in place of Resend's SDK, keeping the same from-address once DNS has propagated.
4. **Import any audience you manage outside Resend** as a CSV, since Resend itself has little list functionality to export.
5. **Turn off Resend once send volume on SES is stable**, rather than cutting over mid-campaign.

## FAQ

**Is SendBunny a Resend clone?**

No. Resend is a hosted transactional email API on its own cloud. SendBunny is a full platform, campaigns, templates and a transactional API, that you install into your own AWS account for $199 once, sending through your own Amazon SES.

**Do I still get a developer-friendly send API on SendBunny?**

Yes. Every install ships a [REST transactional API](https://sendbunny.co/docs/send-email-api): create a key in the dashboard, then POST a from, to, subject and body, or reference a stored template by alias with merge data. Suppression is enforced on that path automatically.

**At what point does SendBunny beat Resend on cost?**

Once monthly volume runs meaningfully past Resend's Pro-tier allowance. At a million emails a month, Amazon SES runs around $100 against Resend's Scale-plan pricing near $650, with SendBunny's $199 already paid off.

**Do I have to manage Amazon SES myself if I switch?**

The app handles domain verification, DNS records and sandbox status for you. New AWS accounts start in the SES sandbox limited to verified addresses; the dashboard shows that status and links directly to AWS's production-access form.
