Why use MailerSend rather than the emails in WooCommerce?

WooCommerce uses its own native system to send order notifications, but sometimes emails can end up in the spam folder or get delayed. MailerSend takes care of your domain reputation so your emails reach your customers safely. Plus, you get a dashboard that shows you important data about your emails and how their performance can be improved.

Is this plugin free?

Yes! And you can send up to 3,000 emails/month with MailerSend for free as well. For a higher volume of emails, you can pick from pay-as-you-go plans without long-term commitments. Premium plans start from $30/month for 50,000 emails/month.

I’m using MailerSend for a a few WooCommerce projects I have and it’s been a pleasure setting it up, creating emails and having high deliverability. Highly recommended.
April 12, 2023
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 SMTP 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.
