Which one is for you

Pick Mailgun if

  • Fits if your app needs to receive email and pass it on to a webhook
  • Works for teams whose email data has to stay in the EU

Look elsewhere if

  • Tight if you're on Free or Basic, with 1 sending domain and 1 day of logs
  • Not for you if you want an editor to write and send campaigns, since it's all code
  • Pricey if you need a dedicated IP, which starts with Scale at $90 a month, with extra IPs at $59 each
  • Watch out: inbox placement tests and reputation monitoring are a separate product, Mailgun Optimize
  • Watch out: Free stops at 100 emails a day, and Basic charges $1.80 per 1,000 past 10,000

Pick SendLayer if

  • Fits if you run a WordPress or WooCommerce site and send order mail
  • Works for small senders under 10,000 emails a month

Look elsewhere if

  • Skip it if you want a free plan, as there is only a 200-email trial
  • Tight if you want to pay monthly, since every plan is billed annually
  • Watch out: your plan is upgraded automatically when you reach its monthly email limit
  • Not for you if you send marketing campaigns, because it is a transactional service
  • Tight if you need long logs, as Starter keeps 3 days

How we grade them

2.4GPAMailgunFair2.4GPASendLayerFair
Value for money
CGraded on 50,000 emails a month: Foundation is $35 at that volume, toward the dear end of this category, with the first month free. Basic is $15 but stops at 10,000 emails, 1 domain and 1 day of logs. A dedicated IP means Scale at $90.
A$5 a month billed annually for 1,000 emails, under the $6 that is 60% of the category's cheaper quarter. The volume is small and the year is paid up front.
Free plan and trial
CFree for good: 100 emails a day through the API or SMTP, with 1 domain, 1 inbound route and 1 day of logs. Enough to build against, not to run a live app on. There's also a 30-day trial of Foundation and Scale.
DA trial of up to 200 emails and no permanent free plan; the page does not say whether a card is needed.
Features
BAPI and SMTP with SDKs in six languages and an MCP server, inbound routing, webhooks, templates, address validation, US or EU regions and dedicated IPs. It covers the job; inbox placement tests are a separate product, Mailgun Optimize.
CSMTP and an API, email logs, open and click tracking, suppression and domain authentication, but the listing shows no inbound mail or IP pools and logs last 3 to 30 days.
Ease of use
CJudged on how fast a developer sends a first email: grab an API key, use an SDK or SMTP, and verify a sending domain. No rating on record. There's no send button at all, so everything goes through code.
CNo store rating on record. You verify a sending domain with DNS records and wire up SMTP credentials or an API key before the first email goes out.
Platforms and integrations
BWeb, with an API, SMTP, SDKs and an MCP server, plus Zapier, Make, n8n, Shopify, HubSpot, Salesforce, WordPress and Datadog. No desktop or phone app, so B is the top.
BA web dashboard and an API; the listing names WordPress and WooCommerce.

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
