What it does
Sending newsletters straight from a web server often causes trouble: messages fail to go out or end up in spam folders. The Newsletter - SMTP.com Delivery Addon handles this by handing your outgoing email to SMTP.com, a service built for email delivery. Your newsletter keeps working as before inside WordPress, while the actual dispatch runs through SMTP.com's servers and their authentication methods. Setup is handled through a settings interface, so you can connect the service without editing code.
Once connected, you get control over how mail is sent. You can manage sending limits, retry attempts and server settings to suit your campaigns. The addon also reports on delivery success, open rates and engagement, and it keeps error logs so you can find out why a message did not go through. It suits sites that send anywhere from a few hundred emails to many thousands and want their newsletter delivery handled by a dedicated provider.
Best for
- Sites sending regular newsletters from WordPress
- Businesses with growing subscriber lists
- Site owners troubleshooting failed or spam-flagged emails
