Mailburger vs Mailgun
Sinch Mailgun is an email API and SMTP relay for developers sending transactional and programmatic email at volume, with no campaign tool of its own. Mailburger is an email marketing tool for newsletters, signup forms and automations, and works alongside Mailgun rather than replacing it for app email.

Switching
Moving from Mailgun, step by step
This guide moves your marketing email (newsletters, announcements, drip emails) to Mailburger. Receipts, password resets and other app email stay on Mailgun.
1. Decide what moves
List the emails your code sends through Mailgun and split them in two. App email that one person triggers by using your product stays on Mailgun. Anything you send to a list of subscribers moves to Mailburger.
2. Export your subscribers
Export the people who agreed to receive marketing email, from your own database or from your Mailgun mailing lists, as a CSV with their names and any fields you personalise with. Leave out anyone who unsubscribed.
3. Recreate fields and import
Create your custom fields under Audience → Custom fields, create an audience for each list, then import each CSV. Tags can be added during the import.
4. Translate template variables
Mailgun batch sends use recipient variables such as %recipient.first_name%, and stored templates use Handlebars variables such as {{first_name}}. Here the first name is {{first_name}}, with a fallback such as {{first_name|there}}, and custom fields are {{custom.your_field}}. See merge tags. Rebuild the layout in the drag-and-drop editor so you no longer maintain the HTML in code.
5. Replace send scripts with campaigns and automations
Scheduled newsletter scripts become campaigns you send or schedule from the app. Drip logic in your code becomes automations, with delays, if/else branches and waits for an open or click. Recreate your audience filters as segments.
6. Connect your app
Send new signups to our REST API: POST /api/v1/contacts upserts by email. Product events can be recorded as custom events that start automations. Your Mailgun integration for app email stays as it is.
7. Verify a sending subdomain and warm up
Verify a sending domain for marketing, ideally a subdomain such as mail.yourbrand.com, so its reputation stays apart from the domain your app email uses. Start with your most engaged subscribers; our guide on warming up a domain explains how.
Questions
Asked at the counter
Can Mailburger replace Mailgun?
For marketing email, yes; for app email, no. Mailburger has no transactional API or SMTP relay, so keep Mailgun for receipts and password resets and use Mailburger for newsletters and automations.
Does Mailgun have a free plan?
Yes: 100 emails a day, 1 custom sending domain and 1 day of logs, with no card needed. Without a card on file you can only use the sandbox domain and send to up to 5 authorised recipients.
Can I send newsletters through Mailgun?
Mailgun's pricing FAQ says there is no send button. You can send to mailing lists through its API, but signup forms, segments and automations are yours to build.
What does Mailburger cost at 100,000 emails a month?
Pro is €20 a month for up to 50,000 contacts and 500,000 emails. At the same volume Mailgun Foundation 100k is €69, but that covers app email, which Mailburger does not send.
Will my newsletters affect my app email?
Sending marketing from its own subdomain, such as mail.yourbrand.com, keeps its reputation apart from your other mail. Mailburger verifies that domain with SPF, DKIM and DMARC records.
How do I move newsletters from Mailgun to Mailburger?
Export your subscribers from your app or your Mailgun mailing lists as CSV, import them into an audience and recreate your fields. Keep Mailgun's API for app email. The step-by-step guide is on this page.
