Which one is for you
Pick Lettermint if
- Fits if you need your mail data kept in the EU
- Works for small apps that fit in 10,000 emails a month
Look elsewhere if
- Tight if you stay free, since 300 emails a month, 1 domain and 1 user is the cap
- Watch out: prices are in euros and billed in euros
- Watch out: a dedicated IP is a €50 a month add-on, Pro only, from 300,000 emails a month
- Watch out: written SLAs and bring-your-own-IP are for enterprise customers on Pro
- Pricey if you go over your plan, at €1.10 to €1.50 per extra 1,000 emails
Pick Resend if
- Fits if you build in React or Next.js and want emails written as components
- Works for apps or AI agents that need inboxes that send and receive by API
Look elsewhere if
- Pricey if you need a dedicated IP, at $30 a month on top of the $90 Scale plan and over 3,000 emails a day
- Tight if you need SSO, which is a $150 a month add-on on Scale
- Skip it if you want to pay yearly for a discount, since billing is monthly only
- Watch out: the free plan stops at 100 emails a day, and the next step up is Pro at $20
- Watch out: marketing email is priced separately by contacts, from $40 a month for 5,000
How we grade them
| 2.6GPALettermintGood | 2.6GPAResendGood | |
|---|---|---|
| Value for money | B€10 a month for 10,000 emails, at the cheaper end of a category whose cheaper quarter tops out at $10. | BGraded on 50,000 emails a month: Pro is $20 for exactly that, in the lowest-priced quarter of this category at that volume, with 10 domains and no daily limit. There's no yearly discount, and extra emails are $0.90 per 1,000. |
| Free plan and trial | CA free plan of 300 emails a month, 1 domain and 1 user with no card; a live app will pass that quickly. | CFree for good: 3,000 emails a month, but only 100 a day, with 3 domains, 1 webhook and 30 days of logs. Marketing email is free up to 1,000 contacts too. A launch day with more than 100 sign-ups hits that daily cap. |
| Features | BTransactional, broadcast and inbound mail in one account, SMTP and a REST API with SDKs, managed IP pools, suppression and a sandbox mode. | BAPI, SMTP, SDKs, React Email templates, inbound email and inboxes for AI agents, signed webhooks, a test mode and broadcasts. It covers the job. No address validation is on record, and dedicated IPs need Scale. |
| Ease of use | CNo store rating on record. You verify a sending domain with DNS records and wire up SMTP credentials or an API key before the first email goes out. | CJudged on how fast a developer sends a first email: SDKs for most languages and React templates for web developers, and test mode fakes events without emailing anyone. You still verify a domain first. No rating on record. |
| Platforms and integrations | BA web dashboard and an API; the listing names Laravel, Symfony Mailer, WordPress, Node.js and PHP. | BWeb, with an API, SMTP, SDKs and MCP, and it works with Next.js, Remix, Nuxt, Express, Hono and Astro. No desktop or phone app, so B is the top. |
| Best for | EU-hosted transactional and broadcast email | developers building with React and Next.js |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
