Mailgun is a well-established email service, and plenty of products send through it. But its own site describes it as a transactional email service for developers, and it shows. If you build with Claude Code and don't write code yourself, you may want a Mailgun alternative that fits the way you work.

Transactional emails are the automatic, one-to-one messages your project sends, such as sign-up confirmations, password resets and receipts. (Here's more on what a transactional email service is.)

This guide covers why people look beyond Mailgun, what setting it up and running it involves, the main alternatives with prices checked in October 2026, and which one suits a non-technical builder.

Why do people look for a Mailgun alternative?

Most people looking for a Mailgun alternative aren't unhappy with delivery. They find the product is built around developers, and the free plan is tighter than it first looks.

  • It's made for people who code. Mailgun's own pricing FAQ points out that it has no send button. Email goes out from your project's code, and the docs and dashboard assume you're comfortable with API keys, DNS records and webhooks.
  • The free plan is small. It allows 100 emails a day from one custom sending domain, and keeps logs (the record of what was sent) for one day. That's short if a customer tells you two days later that an email never arrived.
  • Testing has limits. Every new account gets a sandbox domain, a test address Mailgun provides. It can send to no more than five approved email addresses, so real users need your own domain set up first.
  • Its AI connection runs on your computer. Mailgun offers an official MCP server (MCP is explained here): a connector that lets AI tools like Claude work with your Mailgun account. Mailgun says it doesn't offer a hosted version, so you install developer tools and paste your API key into a settings file to use it.

What is setting up Mailgun like?

Mailgun setup follows the same pattern as most email services:

  1. Create an account and choose a plan.
  2. Add your sending domain, for example mail.yourcompany.com.
  3. Add DNS records where your domain is registered. DNS records are small settings that tell the internet your domain allows Mailgun to send for it. Mailgun's docs list two TXT records (SPF and DKIM, which prove emails really come from you), a CNAME record for tracking, and MX records for receiving email. Changes can take 24 to 48 hours to spread, then you verify the domain in Mailgun.
  4. Create an API key, a long password-like code that lets your project use your Mailgun account (what an API key is), and store it safely in your project.
  5. Ask Claude Code to add the sending code and send a test.

Mailgun's docs are thorough, and Claude Code can help with the last two steps. If the domain step is where you're stuck, see how to verify a domain for email.

What is working with Mailgun day to day?

Once it's running, daily work happens in the Mailgun dashboard. That's where you check logs, manage domains and templates, and review suppressions (addresses Mailgun has stopped sending to after bounces or complaints).

How far back you can look depends on your plan. Logs are kept for 1 day on Free and Basic, 5 days on Foundation and 30 days on Scale.

The MCP server can take some of this into a chat. Once it's connected, Claude can send messages, query delivery stats and check DNS settings. For a developer, that's a useful shortcut. For everyone else, the install itself is the hurdle, and the tools still expect you to know which settings to change.

What are the main Mailgun alternatives?

Here are the services people most often compare with Mailgun.

Resend is a newer developer-focused service. Its free plan covers 3,000 emails a month (up to 100 a day), and Pro costs $20 a month for 50,000 emails. Resend runs a hosted MCP server: you can add it from Claude's connector directory, or as a custom connector in Claude's settings, then log in to Resend. Read more in our Resend alternatives guide.

Postmark focuses on transactional email. Its free plan includes 100 emails a month, and Basic starts at $15 a month for 10,000 emails. Postmark has an official MCP server, which you add to your AI tool with a snippet of settings from its GitHub page.

SendGrid, now part of Twilio, offers a 60-day free trial with up to 100 emails a day. Paid Essentials plans start at $19.95 a month. For a closer look, see SendGrid vs Mailgun.

Amazon SES is the cheapest per email. Pay-as-you-go sending costs $0.10 per 1,000 emails, and new accounts start on its Essentials plan at $0.16 per 1,000. New accounts also begin in a sandbox: you can send only to verified addresses, up to 200 emails a day, until you request production access and AWS reviews it.

SimpleSends is a transactional email service built for people who build with Claude Code but don't write code. More on how that works below.

How is SimpleSends different for people who don't code?

Under the hood, SimpleSends works like the other services. You still have an account, a verified sending domain, a secret key your live project uses, and a small piece of sending code in your project. What's different is who it's built for and where your daily work happens.

  • Written for people who aren't developers. The sign-up, connect steps and help are in plain English, without developer jargon.
  • Everything after sign-up happens in the chat. You don't need a dashboard for day-to-day work. You brief Claude Code the way you'd brief a person.
  • Claude Code does the whole job. It designs, writes, builds and changes every transactional email: welcome, password reset, receipts and the rest. "Set up all my transactional emails" is a reasonable brief.
  • Problems get sorted in plain English. Claude Code can read send logs and delivery status through SimpleSends, so it can tell you whether an email went out and help work out why one didn't.

For example:

Tell Claude Code

A customer says they never got their password reset email yesterday afternoon. Can you check whether it went out and explain what happened?

Claude Code looks up that send and tells you whether it was delivered, bounced or never sent, and what to do next.

One thing stays the same as with any service: once your project is live, real emails go out from your project directly. Claude Code is involved while you're building and changing things, not each time a customer gets an email.

Which Mailgun alternative is best for non-technical builders?

The best fit depends on who will do the work.

  • You or a developer want to edit code yourself: Mailgun, Resend and Postmark are all solid developer tools.
  • You send very high volumes and price per email matters most: Amazon SES costs least, if you're comfortable with AWS.
  • You build with Claude Code and don't write code: SimpleSends is built for you.

How do you switch to SimpleSends?

  1. Sign up on the SimpleSends website and follow the steps there to set up the email address you'll send from. To send from your own domain, this includes adding a few DNS records where your domain is registered. You can't sign up inside the Claude Code chat.
  2. In Claude Code, open Customize, then Connectors, choose Add, then Add custom connector. Fill in the fields below.
  3. When Claude prompts you to connect, log in to SimpleSends.
  4. Back in the Claude Code chat, tell Claude Code: "I've connected SimpleSends for all transactional email." It takes it from there, including adding what your project needs to send email.

MCP server URLhttps://mcp.simplesends.com/mcp

If your project already sends through Mailgun, add a brief like this:

Tell Claude Code

My project currently sends its emails through Mailgun. Please move all of them to SimpleSends, keep every email we send today, and send me a test of each one so I can check them.

Claude Code lists the emails your project sends, switches them over and sends you a test of each one to review.

Frequently asked questions

Is Mailgun free?

Mailgun has a free plan that sends up to 100 emails a day from one custom sending domain, with logs kept for one day. New accounts also get a sandbox domain for testing, but it can send to no more than five approved addresses. Paid plans start at $15 a month for 10,000 emails (checked October 2026).

Who owns Mailgun?

Mailgun is part of Sinch’s email group, alongside Mailjet and Email on Acid. Its site and documentation now carry the Sinch name. Day to day, the product and plans work as a standalone email service with its own account, dashboard and pricing.

Does Mailgun work with Claude Code?

Yes. Mailgun has an official MCP server that lets Claude send emails, check delivery stats and inspect domains. It runs on your own computer, not as a hosted service, and setting it up means installing a developer tool called Node.js and adding your Mailgun API key to a settings file.

Can I keep my domain if I switch away from Mailgun?

Yes. Your domain stays yours. You add the new service’s DNS records where your domain is registered and verify them. Once nothing sends through Mailgun anymore, you can remove its sending records. Keep its MX records only if Mailgun still receives email for that domain.

How long does switching email services take?

Most of the wait is the domain step. After you add the new DNS records, they can take up to 24 to 48 hours to spread across the internet, though it’s often faster. Updating your project and testing each email usually takes far less time than that.
