As a web developer, one of the features that cannot be omitted in almost any app is the ability to send emails. For example a confirmation email when you sign up, a reset password message, a notification of a new message, etc…
You can use an ordinary email service for that, such as Gmail or Outlook, but chances are that these services are not enough for that purpose, because of some rate limits those services use to have.
That kind of messages are known as transactional emails and there are a lot of services dedicated to that. Do not confuse these kind of emails with marketing emails, which are bulk message services to send marketing messages and newsletters. Let’s see some of the best transactional email services.
Sendgrid
They have a free tier of 100 emails per day and then starts at $19,95/month
AWS SES
This is probably one of the cheapest services at $0,19/1000 emails. AWS has also a time limited free tier but I think it is not specific of the email service. I may end using this if I need a paying service.
Resend
It has a free tier of 3000 emails/month (100 emails/day) and then starts at $20/month
Postmark
Free for 100 emails/month, and then starts at $15/month
Asana
Mailgun
This one has a strange free tier. You can send 5000 emails/month for free but only to 5 contacts. Then starts at $35/month. This is probably the most expensive one and unfortunately is the only one officially integrated in Ghost CMS for newsletter sending.
Mailchimp
This is famous for its newsletter service but they also offer transactional emails. They have a free tier of 500 emails/month and then starts at $20/month.
