Mailgun's free plan caps you at 100 emails a day
Mailgun's free plan allows 100 emails a day, the only volume figure Mailgun publishes for it. Mailfully's free plan sets a monthly allowance of 5,000 emails and a daily cap of 200. Mailgun's Basic plan, the next step up, costs $15 a month for 10,000 emails and has no daily cap.

Mailgun figures from its own pages, checked in October 2026. A new account can send live mail as soon as its domain is verified, and a short review, usually within a day, lets it send more.
What does Mailgun's daily cap mean for your app?
What happens past 100 isn't stated
Mailgun's pricing FAQ calls the 100 a day a daily sending cap, and its free-plan article doesn't say what happens to a send past it.
One custom domain and a 5-recipient sandbox
Mailgun's free plan includes one custom sending domain. Beside it you get a sandbox domain for testing, which sends only to authorized recipients, at most 5 of them.
One day of logs
Logs and event data last 1 day on Mailgun's free plan. You can confirm this morning's test went out; by tomorrow the entry is gone.
When does Mailgun's free plan make more sense?
Mailgun suits a team that sends for many brands. From its Foundation plan up, Mailgun allows more sending domains than our Starter and Growth plans. Its free plan is a way to try the API before you need that. Mailgun also has a self-serve EU region. For an app sending a little over our free 5,000 and up to 10,000 emails a month, Mailgun's $15 Basic plan costs less than our $19 plan.
Questions
- Is Mailgun's free plan really free?
- Yes, Mailgun's free plan costs nothing and doesn't ask for a credit card. Mailgun states no end date for it, and the free trials it offers are on its paid plans.
- How many emails a month does Mailgun's free plan allow?
- Mailgun doesn't publish a monthly figure for its free plan. The only volume it states is the cap of 100 emails a day.
- Do test sends count on Mailgun's free plan?
- Mailgun's documentation says messages sent in test mode are charged, but it doesn't say how that works against the free plan's daily cap. Mailfully's test sends go only to test addresses and never count toward the allowance.
