Businesses need to send transactional emails, and these free services will come in handy for small to mid-level entrepreneurs. Stay tuned.

Emails are ingrained elements of our digital lives. We receive many from the moment we wake up to hitting the bad, and a few also slip in afterward 😅.

While there are many types of emails we send and receive, this is about a specific kind to which every business gives importance.

Transaction Emails

As evident by the name, these emails notify users about significant events like:

  • Account creation
  • Password change
  • Order confirmation
  • Shipping information
  • Invoice, etc.

The bottom line–they are crucial, and you don’t want to miss sending them. And while there are plenty of paid transaction email services, a free plan is something every beginner looks forward to.

So, let’s jump in for some free transactional email services!

Sendinblue

Sendinblue gets you started with its free tier with a generous limit of 300 emails per day. You get responsive email templates customized to your taste and brand voice.
