Why do people look for Mailgun alternatives?
Most people searching for Mailgun alternatives are not shopping — they already run it and something has stopped fitting. That something is usually a specific number rather than a feeling, so this page starts from the fields where Mailgun genuinely trails the rosters it appears in, and only then covers the reasons that never show up in a table.
The measured reasons.
- Log retention — 1440 min, 8th of 9. Postmark records 64800 min.
- Dedicated IP — $59 /mo, the weakest of the 7 here. Amazon SES records $24.95 /mo.
- Price / 1k emails — $1.5 /1k, 8th of 11. Amazon SES records $0.1 /1k.
Any one of those is enough on its own if you sized your architecture around it. None of them is enough if you didn't — which is why the list is short and specific rather than a general case against Mailgun.
The reasons that never make it into a table. A price rise after a funding round. A licence change that turns a self-host into a subscription. A region you now need and they do not have. An acquisition. A support experience that quietly degrades. None of those are fields, and all of them move teams — which is why every entry below links back to Email APIs, where the full field set and its sources live. The ones we catch get logged on the Mailgun timeline.
How the shortlist is ordered. Every tool below shares at least one comparison category with Mailgun, sorted by how many categories the two overlap in. There is no editorial ranking, no sponsorship and no affiliate link — the order is the overlap count, and the rationale under each is generated from the two tools' own cells, so it names real values rather than adjectives.
1.AhaSend
AhaSend — Small indie transactional API competing on price and instant signup. It meets Mailgun in Email APIs. It is ahead on llms.txt docs (Yes against No), GA year (2023 against 2010) and DKIM/DMARC friction (2 against 3). What you give up: Hosted templates (none, where Mailgun records visual-editor) and Funding (bootstrapped, where Mailgun records subsidiary). Best for side projects and internal tools where price dominates. Cheap, fast to start, and small enough that you are trusting one team's operational discipline with your sending reputation. Reasonable for internal tooling and side projects; think harder before it carries your password resets.

2.
Amazon SES
Amazon SES — The cheapest way to send email at scale, and the least finished product. It meets Mailgun in Email APIs. It is ahead on Price / 1k emails ($0.1 /1k against $1.5 /1k), Data residency (us, eu, au, apac, sa, ca against us, eu) and Dedicated IP ($24.95 /mo against $59 /mo). What you give up: Time to first send (2880 min, where Mailgun records 30 min) and Hosted templates (api-only, where Mailgun records visual-editor). Best for high volume where $0.10 per thousand actually moves the P&L. An order of magnitude cheaper than everything else and roughly half a product. Correct above a couple of million messages a month, or when Sydney data residency is non-negotiable; a poor trade below that once you cost the dashboard you will end up building.

3.
Brevo
Brevo — EU-hosted marketing platform with a competent transactional API attached. It meets Mailgun in Email APIs. It is ahead on Log retention (43200 min against 1440 min), Free tier (9,000 emails/mo against 3,000 emails/mo) and Product scope (marketing-first against transactional-first). What you give up: IP warmup (Partial, where Mailgun records Yes) and Shared pool quality (2, where Mailgun records 3). Best for EU-only data residency without self-hosting. Buy it for the EU hosting and the marketing suite, not for the transactional API. The free tier is the largest here and the shared pool reflects exactly that. Manual account validation makes it a poor choice if you need to be live today.

Loops
Loops — Lifecycle and marketing email for SaaS, priced on contacts rather than sends. It meets Mailgun in Email APIs. It is ahead on llms.txt docs (Yes against No), GA year (2023 against 2010) and Product scope (marketing-first against transactional-first). What you give up: IP warmup (No, where Mailgun records Yes) and Inbound parsing (No, where Mailgun records Yes). Best for onboarding sequences and product announcements. The best-looking way to send lifecycle email, and the wrong tool for high-volume transactional. Contact-based pricing is a bet that your list stays engaged; if you accumulate dormant signups, the bill grows for mail you never send.

5.
MailerSend
MailerSend — Transactional sibling of MailerLite, bootstrapped and cheap at mid volume. It meets Mailgun in Email APIs. It is ahead on Log retention (43200 min against 1440 min), Price / 1k emails ($0.56 /1k against $1.5 /1k) and React Email / MJML (handlebars, mjml against handlebars). What you give up: Time to first send (1440 min, where Mailgun records 30 min) and Funding (bootstrapped, where Mailgun records subsidiary). Best for mid-volume sending where SES is too raw and Postmark too dear. The best price per message once you are past 50,000/month and want a real UI, undercut only by SES and the indies. The manual approval gate is the tax — fine if you are planning a migration, painful if you are shipping tonight.

6.
Mailtrap
Mailtrap — Email testing sandbox that grew a production sending product. It meets Mailgun in Email APIs. It is ahead on Log retention (43200 min against 1440 min), DKIM/DMARC friction (2 against 3) and GA year (2013 against 2010). What you give up: Inbound parsing (No, where Mailgun records Yes) and Funding (bootstrapped, where Mailgun records subsidiary). Best for catching and inspecting outbound mail in staging. Worth having for the testing sandbox regardless of who sends your production mail — it is the cleanest way to inspect rendered email in staging. The sending product is fine, not distinctive, and younger than the pool-quality question deserves.

7.
Plunk
Plunk — Open-source email console you self-host on top of your own AWS SES account. It meets Mailgun in Email APIs. It is ahead on GA year (2023 against 2010), Multi-domain sending (Yes against Partial) and Price / 1k emails ($1 /1k against $1.5 /1k). What you give up: IP warmup (No, where Mailgun records Yes) and Inbound parsing (No, where Mailgun records Yes). Best for teams who already run SES and want a UI over it. The cheapest honest way to get a dashboard, contacts and campaigns on top of SES pricing, and the only option here that puts message data in your own database. You take on the deployment and SES's onboarding at the same time.

8.Postmark
Postmark — Transactional-only sender with the best-policed shared IP pool in the category. It meets Mailgun in Email APIs. It is ahead on Log retention (64800 min against 1440 min), Shared pool quality (5 against 3) and React Email / MJML (mjml, handlebars against handlebars). What you give up: Free tier (100 emails/mo, where Mailgun records 3,000 emails/mo) and Data residency (us, where Mailgun records us, eu). Best for password resets, receipts and anything a support ticket follows. Still the deliverability benchmark, and the only vendor here whose pool quality is a deliberate business decision rather than a side effect. Expensive, opinionated, and worth it for mail that must arrive.

How this list was built
There is no editorial ranking on this page and no sponsorship behind it. The order is mechanical: every tool that shares a comparison category with Mailgun, sorted by how many categories the two overlap in. A tool that meets Mailgun in three rosters sits above one that meets it in a single roster, because more overlap means the comparison is more like-for-like.
The rationale under each entry is composed from the two tools' own cells. Where they differ on a field we score, the sentence names both values and the unit. Where they don't differ, it says so instead of manufacturing a distinction — which is why some entries are short.
Values, sources and verification dates all live on the category tables: Email APIs. If a figure here disagrees with a vendor's current pricing page, the vendor is right and we are stale.
Still deciding whether to move at all? The Mailgun profile has the when-to-use and when-not-to-use blocks, and the Mailgun timeline has the dated changes that usually trigger a migration.
