As far as I could see, the plugin seems to work Ok, it’s a shame I can’t say the same for the ‘practices’ of the company.
Great Plugin Needs Some Polish
by savagemic·2 years ago·1 reply
The mailersend application is fantastic. I can’t speak highly enough about deliverability and functionality.
However, if you are using this as a transactional email system for WooCommerce you cannot use the mailersend templates (which are particularly good) and have Mailersend send other WordPress-related emails, such as comment notifications and other emails such as Gravity Form entries.
You cannot run this plugin and the MailerSend WooCommerce plugin together as it will create a critical WordPress error on transactional email sends.
This seems like an oversight and I’m not really sure why these two plugins cannot be one and handle not only transactional WooCommerce but also WordPress emails.
Easy to use. Works like a charm!

I don’t understand why reviewers gave this plugin a negative review “for not working” because it works perfectly. They must have forgotten to verify their account with MailerSend.
The domain verification and account approval took less than a day to complete and I could send out emails in a blink of an eye. I switched to MailerSend because my Namecheap SMTP took twice the amount of time to post my contact form. With MailerSend, form submission takes 3-4 seconds.
Kudos and thumbs up to the developers! I highly recommend MailerSend!
