Service providers such as Amazon SES are reliable and have complete infrastructure for email delivery.
We recommend configuring the following email service providers:
- Amazon SES
- Elastic Email
You can integrate your email service provider with these plugins.
WP Offload SES Lite, WP Mail SMTP, Postmark for WordPress, or Elastic Email Sender effortlessly configure your WordPress site to send all the emails using the provider’s direct API.
These plugins resolve your email delivery issues by reconfiguring the wp_mail () function to either make use of proper SMTP host credentials or leverage the built-in SMTL email provider.
Now, even if your web hosting server is blocking the SMTP ports, your emails will still be sent successfully.
For example, Google allows 2000 emails/day and 500 email/day for trial account. Also, they are meant for one to one communication and not bulk (one to many).
