Mailgun and Mailburger both send email and both have an API, so they can look alike. In practice they do different jobs. Mailgun delivers the email your application sends. Mailburger is where you write, schedule and automate the email your marketing team sends. This comparison, based on public pricing checked in October 2026, explains where the line sits.
The short answer
Keep Mailgun, or another API provider, for app email: receipts, password resets and notifications. Mailburger does not send those. Use Mailburger for newsletters, welcome series and other campaigns, because Mailgun's own pricing FAQ says there is no send button: lists, segments, signup forms and automations would otherwise be code your team writes and maintains. You can run both, with marketing on its own sending subdomain.
The side-by-side tables are on Mailburger vs Mailgun.
What each one is
Sinch Mailgun is an email API and SMTP relay for developers and product teams sending transactional and programmatic email at volume. It includes templates with a drag-and-drop or HTML editor, webhooks, inbound routing and analytics, and sells deliverability monitoring (Optimize), list validation (Validate) and email previews (Inspect) as separate products. It offers US and EU regions in one account.
Mailburger is an email marketing tool for newsletters, signup forms and automations, running on its own delivery engine. Every plan includes a drag-and-drop editor, templates, signup forms with double opt-in, segments and campaign reports. Paid plans add automations, A/B tests, contact scoring, AI help and a REST API for syncing contacts and recording events. Plans are priced in euros by subscribed contacts and monthly emails, billed monthly with no contract.

Monthly list prices. Mailgun also lists USD and GBP.
These numbers are not a like-for-like contest, because the two products do different work. The useful question is what it costs to move your marketing volume off your API provider, and what you would otherwise have to build.
How Mailgun bills. Each plan includes a number of emails a month, and extra emails are billed per 1,000. Basic is €14 for 10,000 emails with €1.70 per extra 1,000; Foundation 50k is €32 with €1.20; Foundation 100k is €69 with €1.00; Scale 100k is €82 with €1.00, and Scale 500k is €363. You pay a prorated amount at signup, then the plan fee and the previous month's overage at the start of each month. Foundation and Scale come with the first month free. Validations are billed separately, per 100.
How Mailburger bills. Plans count subscribed contacts and contacts pending double opt-in, plus a monthly email allowance. Unsubscribed and bounced contacts do not count, and test sends and confirmation emails do not use your allowance. Grow covers 5,000 contacts and 50,000 emails a month for €5, and Pro covers 50,000 contacts and 500,000 emails for €20. If your list is larger than the plan's contacts, pick the plan by contacts first. Every plan is on our pricing page.
Free plans. Mailgun's Free plan sends 100 emails a day with 1 custom sending domain and 1 day of logs. Without a card on file you can only use the sandbox domain and send to up to 5 authorised recipients. Mailburger's Free plan covers 500 contacts and 2,500 emails a month.
Deliverability and sending
Mailgun includes one dedicated IP from Foundation 100k and on Scale, with extra IPs at $59 each a month, automated IP warm-up from Foundation and IP pools on Scale. Send Time Optimization is Scale only. Logs are kept for 1 day on Free and Basic, 5 days on Foundation and 30 days on Scale. Inbox placement tests and reputation monitoring are not part of any sending plan; they need Mailgun Optimize, from €45 a month. A domain's US or EU region cannot be changed after it is created.
Mailburger sends through its own delivery engine. You verify your sending domain with SPF, DKIM and DMARC records, every campaign carries one-click unsubscribe headers, and signup forms support double opt-in, business-email validation and spam protection with a built-in proof-of-work check or Cloudflare Turnstile. Reports include click maps. Mailburger does not offer dedicated IPs. Sending marketing from a subdomain such as mail.yourbrand.com keeps its reputation separate from the domain your app email uses.
Team, security and agencies
Mailgun allows unlimited users from Foundation, with five roles, and two-factor authentication on every plan. SAML single sign-on with just-in-time provisioning starts on Scale. Foundation and up allow up to 1,000 sending domains, and subaccounts with their own domains, IPs and keys are Enterprise only.
Mailburger includes 3 team members on Grow and unlimited members on Pro, along with SAML single sign-on and a workspace audit log. Agencies can use the Agency plan at €49, which pools 100,000 contacts and 1,000,000 emails across up to 25 white-label client workspaces, or Agency Plus at €149 with 500,000 contacts, 5,000,000 emails and unlimited clients.
Support
Mailgun offers ticket support on Free, Basic and Foundation. Scale adds live chat and phone support, and Enterprise gets managed support.
Mailburger offers email support on every plan, with priority support on Pro.
Who should choose which
Keep Mailgun if:
- your application sends receipts, password resets, alerts or other one-to-one email,
- you need SMTP, inbound routing or webhooks for app workflows,
- you need US and EU sending regions in one account.
Choose Mailburger for:
- newsletters, announcements and promotions to a subscriber list,
- welcome series and follow-ups built from triggers and waits instead of cron jobs,
- signup forms with double opt-in that you would rather not build yourself,
- marketers who want to edit and send emails without a developer.
If you have an app and a newsletter, you can run both, each doing the job it was made for.
Switching your marketing email from Mailgun
Start by listing the emails your code sends and splitting app email from marketing. Export your subscribers from your database or your Mailgun mailing lists, import them into an audience, and translate recipient variables such as %recipient.first_name% into {{first_name}}. Then rebuild your newsletters in the editor and your drip logic as automations, and verify a sending subdomain. The full checklist is on Mailburger vs Mailgun.
