Which one is for you
Pick EmailJS if
- Fits if you need a contact form on a static site and have no server
- Works for small sites that send a few hundred emails a month
Look elsewhere if
- Skip it if you need EmailJS to deliver mail, because it only relays through a provider you connect
- Tight if you stay on free, with 200 requests a month, 2 templates and 7 days of history
- Watch out: past your monthly limit, requests are dropped with no overage option
- Watch out: the pricing page toggles monthly and yearly and does not say which one its prices use
- Pricey if you need more than 2,000 requests, since 25,000 is $40 a month
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
How we grade them
| 2.4GPAEmailJSFair | 2.4GPAMailgunFair | |
|---|---|---|
| Value for money | BPaid starts at $9 a month for 2,000 requests, which is the edge of the cheaper quarter of email tools, though the page does not say if that is monthly or yearly billing. | 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. |
| Free plan and trial | C200 requests a month and 2 templates is a cap a busy contact form will reach, and history is kept 7 days. | 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. |
| Features | CClient-side sending, templates, provider switching and SDKs. It does not deliver mail itself, and there are no overage charges: extra requests are dropped. | 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. |
| Ease of use | CNo app rating on record. You connect an email service and wire an SDK or REST call into your code first. | 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. |
| Platforms and integrations | BWeb service with SDKs for JavaScript, React, Vue, Flutter and Node, and connections to Gmail, Outlook, SendGrid, Mailgun and SES. | 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. |
| Best for | contact forms on sites with no backend | sending and receiving email from an app |

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.
- The differences and the answers to the questions are worked out from those listings.
