Resend Alternatives

Postmark is the provider most developers name when they want transactional email that simply arrives. It has been sending app email for well over a decade, and it keeps two kinds of mail apart on purpose: transactional and broadcast traffic run on separate, parallel infrastructure, IP ranges included, so a newsletter that annoys people does not drag your password resets into spam. For a team leaving Resend over deliverability doubts, that separation is the main argument.

The pricing is simple and monthly only. Basic costs $15 a month for 10,000 emails, with extra emails at $1.80 per 1,000. Pro costs $16.50 and Platform $18 at the same volume, and their overage drops to $1.30 and $1.20 per 1,000. Activity is kept 45 days by default; on Pro and Platform, a retention add-on from $5 a month stretches it up to 365 days. The free plan gives 100 emails a month and never expires, but it allows no overage: it is a sandbox for your integration, not a launch plan.

Read that against Resend Pro: $20 buys 50,000 emails at Resend, $15 buys 10,000 at Postmark. You pay more per message. What you get is a provider whose dedicated IPs are fully managed, offered from $50 a month per IP to senders above 300,000 emails a month, and a support team with a strong name among indie developers. One perk worth asking for: a launched, self-funded product that charges customers can ask support for $75 of account credit. Our Postmark vs SendGrid comparison goes deeper on the two incumbents, and the Postmark alternatives page covers the reverse move.

Amazon Simple Email Service is the raw infrastructure many email products sit on, and it is the cheapest serious option on this page. With pay-as-you-go pricing you pay $0.10 per 1,000 outbound emails, plus $0.12 per GB of attachments. There is no subscription and no monthly floor: 100,000 emails cost about $10, where Resend charges $90 on Scale. AWS also sells plan tiers now: Essentials at $0.16 per 1,000, Pro at $0.22 per 1,000 plus $105 a month per account and region, with deliverability tooling and a dedicated IP bundled.

The catch is the work around the send call. A new SES account starts in a sandbox: you can only email verified addresses, at most 200 messages in 24 hours and 1 per second. You then request production access, and AWS Support gives a first answer within 96 hours. There is no visual template editor worth the name, logs live in CloudWatch or event destinations you configure, and support depends on your AWS support plan.

Dedicated IPs are cheap here: $24.95 a month per standard IP, or managed IPs at $15 a month per account plus $0.08 per 1,000 emails. That is the lowest dedicated IP entry on this page, and it needs no plan upgrade.

SendGrid, owned by Twilio, is the incumbent the whole category is measured against. Its Email API covers what you use Resend for (REST API, SMTP relay, dynamic templates, webhooks for events) and Twilio sells a separate Marketing Campaigns product next to it. If your company already pays Twilio for SMS or verification, staying with one vendor is a real argument.

On price it sits close to Resend at the low end. Essentials starts at $19.95 a month and covers volumes from 50,000 to 100,000 emails a month; Pro starts at $89.95 for 100,000 to 2,500,000 emails, with more deliverability tooling. The free plan is gone: what remains is a free trial that lets you send 100 emails a day for 60 days, with no credit card. After that, you pay or you stop.

The complaints we read are less about the API than about the account. Developers on forums describe the end of the permanent free plan as the moment they moved, and SendGrid's shared IPs on the lower plans get mixed reports for inbox placement. The upside is scale: few providers have handled as much volume for as long, and its documentation and SDKs cover almost every language. Teams leaving it for the same reasons as Resend users will find the other side in our SendGrid alternatives guide.

MailerSend is the alternative that feels most like Resend in daily use: a clean dashboard, REST API and SMTP, templates, webhooks, inbound routing and SMS on the same account. Where it differs is the entry price. Hobby costs $7 a month billed monthly, or $6.30 a month billed yearly, for 5,000 emails, with extra emails at $1.50 per 1,000. Starter is $35 a month at the default slider position and Professional, built for agencies and white-label resellers, $110 a month.

The pricing page gives one useful anchor: a $68 Starter subscription includes 100,000 emails, against $90 for Resend Scale. You can also keep sending past your quota, and the extra emails are billed per 1,000, on every plan. Nonprofits get 30% off the paid plans, but the discount does not stack with yearly prices.

The free plan is smaller than Resend's: 500 emails a month, 100 API requests a day and 1 day of log retention. It is enough to wire up your integration, not to run a side project, and it asks for a credit card even though nothing is charged. MailerSend is younger than SendGrid or Postmark, so you have less public history on inbox placement to go on.

Brevo, formerly Sendinblue, is a marketing platform first, with a transactional API and SMTP relay built in. That is the reason to choose it over Resend: one account, one email quota for campaigns and transactional messages, plus automation, SMS, WhatsApp and a CRM if you want them. Resend now sells marketing too, but its marketing plans are priced by contacts, from $40 a month for 5,000, on top of the transactional plan.

Starter costs $9 a month billed monthly for 5,000 emails, or $8.08 billed yearly. Standard is $18 a month. Professional, at $499 a month from 150,000 emails, is the first plan that can add a dedicated IP, as an add-on at $251 a year; Enterprise, from $2,499 a month, includes one. The quota counts campaigns and transactional email together, which is simple, but also means a big newsletter eats into the emails your app needs. Removing the Brevo logo costs $12 a month on Starter. Pay-as-you-go credits do not expire, a rare option for irregular senders.

For developers, Brevo is less pleasant than Resend: the API is complete, but the dashboard is built around campaigns and contacts, not logs and events. Every plan and add-on is broken down in our Brevo pricing guide, and our Brevo alternatives cover the marketing side.

Mailgun, owned by Sinch, has been a developer email API for years and covers the same ground as Resend, plus a strong inbound side: routes that parse incoming mail and post it to your webhook. Basic costs $15 a month for 10,000 emails, with extra emails from $1.80 per 1,000 and no daily email limit. Foundation costs $35 for 50,000 emails, with overage from $1.30 and 5 days of logs, and Scale $90 for 100,000, with overage from $1.10 and up to 7 days of message retention. Both are free for the first month.

The dedicated IP math is where Mailgun can beat Resend. One dedicated IP is included with Foundation 100k, Growth and Scale plans; additional IPs cost $59 a month each. At Resend you pay $90 for Scale plus $30 for the IP. The free plan, on the other hand, is tight: 100 emails a day, 1 custom sending domain and 1 day of log retention.

Field reports are mixed. Mailgun gets credit for its API and its validation add-on, but in 2026 a developer on a web development forum said it had dropped almost 40% of their email to Outlook for a period, and others in the thread asked for alternatives. If you are weighing that move, our Mailgun switching guide lists where its users go.

Mailtrap began as an email testing tool: a fake inbox that catches what your staging app sends, so nobody emails real customers by mistake. It now sells a production Email API and SMTP next to that sandbox, and for a team leaving Resend the pairing is the point. You test templates, spam scores and HTML in the sandbox, then send for real from the same account and the same SDKs.

The free sending plan beats Resend's in monthly terms: 4,000 emails a month, with no credit card, but capped at 150 a day. Basic costs $15 a month for 10,000 emails, Business $85 for 100,000 with a dedicated IP and automatic warm-up, and Enterprise $750 for 1,500,000. Yearly billing saves up to 20%: Basic is then $12 a month, billed annually. The quota is shared between sending and receiving.

Watch the limit behavior. On the free plan, sending stops at the monthly limit with the SMTP error "535 5.7.0 Monthly messages limit reached" until you upgrade or the month resets. Paid plans keep sending and bill extra emails at $1 per 1,000 on Basic, $0.88 on Business and $0.55 on Enterprise, but overages are capped: for a big spike, Mailtrap tells you to upgrade.
