The Free plan gives 500 emails a month, 1 domain, 1 template, 1 API token, 1 webhook, 100 daily API requests and 1 day of activity data. MailerSend's FAQ says it asks for credit card details on the Free plan to prevent abuse and that you will not be charged.

👍 Good boy
+A 14-day trial gives access to Professional features, and when it ends you are not charged or upgraded. You move to the Free plan.
+Capterra reviewers repeatedly praise support. One review reads that the service is inexpensive with a generous free tier and that support is excellent, well trained and quick.
+Another Capterra reviewer who switched from a large provider said support had short response times and technically competent contacts, and that deliverability and reliability mattered most to them.
+A reviewer who hit hard bounces from placeholder addresses said support explained a fix through the Email Verification API and restored the account the same day.
+Overage does not stop sending. Extra emails cost $1.30 per 1,000 on Starter and Professional and $1.50 on Hobby, per the pricing page.
+Nonprofits can get a 30 percent discount on paid plans, and the plans list an MCP server and 7 SDKs.
+Trustpilot shows 4.2 from 230 reviews and G2 shows 4.1 from 46, with G2 summarizing praise for ease of use and responsive support.
👎 Watch out
−The Free plan asks for a credit card and requires account approval. If you want a card-free sandbox, this is not it.
−Free is very small: 500 emails a month, 1 template, 1 domain and 100 daily API requests.
−The Free plan keeps activity data for 1 day, and Starter keeps 7 days. Longer retention is a paid add-on starting at $5.
−A Capterra reviewer titled their review "Would not recommend" and wrote that support responds quickly but is not flexible. Another review, with no title shown in the excerpt, called support terrible and the service unreliable.
−One Capterra review is titled "Great product, could be costly at Scale". The text was not in the excerpt we read, so check the overage math for your volume.
−MailerSend can be strict on deliverability. One reviewer had the account restored only after explaining hard bounces from placeholder addresses.
−Dedicated IPs are only for Enterprise accounts that send over 100K emails a week, per the pricing page.
The catch
The Free plan needs a credit card and an approved account. MailerSend says the card is there to prevent abuse and that you will not be charged for Free.
The trial is separate: 14 days of Professional features with 500 emails a month, 100 API requests a day and 1 day of logs. At the end you are moved to Free, not charged.
Free is a testing tier. One template, one domain and one-day activity data mean you will upgrade to Hobby ($6.30 yearly, $7 monthly) once you send real mail.
Support is the review headline. Capterra and Trustpilot reviewers praise quick, knowledgeable replies, while a small number describe support as inflexible. One reviewer's account was restored the same day after a bounce problem.
