Reliable transactional email service for WordPress

Improve deliverability and ensure your WordPress emails quickly reach the inbox. Start sending in minutes with the WordPress SMTP plugin.

MailerSend
Snappy mail delivery without any backlogs like SendInBlue. I had trouble with WPmail for my WordPress site for quite some time. I gave MailerSend a try when I faced some limitations in SendInBlue (only 300 emails per day and it blocked emails when they were sent too frequently). MailerSend worked like a charm.
AJ V. Product Developer, digiajay.com, A replacement for WPmail worked like a snap
Mailersend was easy to set up and add to my website. I can be sure that my transactional emails go out on time and actually get delivered. Previously I had to use other plugins that required a more complicated setup with Gmail.
