SMTP2GO’s WordPress plugin replaces the default built in wp_mail() functionality (phpmailer) and sends your email via SMTP2GO’s API and industry leading email delivery platform.
SMTP2GO provides valuable insights into every aspect of your email’s life cycle, enabling you to track delivery rates, opens, clicks, and bounce rates. Whether your email is transactional, marketing, newsletter, contact form, or notification – we have got you covered.
The main benefits of using the official SMTP2GO plugin:
Cannot use the plugin with php 8.3, shows critical error. Use another plugin.
Update: yes it was my issue, allow_url_fopen was disabled in php version on the server for some reason.
SMTP has been the bane of my marketing existence forever. I’ve never had such a smooth onboarding. I decided to try it out on my client’s site (loveyourchainlink.com) just to see — since default WordPress emails are tragically and historically a problem.
I’m pretty sure it just took 2 minutes. I’m going to put this on my own site and another client site, too. Wow!
Thank you!
It works like a charm, is so easy to set up compared to the old authentication method, and is lightweight. I highly recommend this gem, and I’m very happy that I found it. I will get a plan when I reach my usage. Please keep the free plan. Big thanks!
It’s the official plugin of the best email sending service out there. The setup is ultra simplified. Forget about messing with DNS, SMTP server, ports. Once you’ve done with your account on their site, it just works fast and reliable out-of-the-box.
A step ahead.
Whatever your email volume, this plugin will meet your needs. I’m on the free plan and the support was still remarkable.
