Understanding SMTP Server for Sending Emails

SMTP or Simple Mail Transfer Protocol is the quickest way to send your transactional and marketing emails using the web app. Because most development frameworks support SMTP, there is no need for extra defined libraries for the integration.Check our SMTP guide to know more.

For developers, Email API seems a great option to send emails. In case this confuses you, read our blog to decide on SMTP vs Email API.


Integrate quickly and Track your emails

SMTP is the fastest way to get started with sending emails. Integrating Pepipost with your application is quite easy as it requires only the modifying of SMTP configuration.
You need to:

  • Change the SMTP username and password to your Pepipost credentials.
  • Set the server hostname to smtp.pepipost.com.
  • You can connect via unencrypted or TLS on ports 25, 2525, and 587.

In SMTP, one mail is sent at a time. All you have to do is connect your mailing server, or servers (if you have multiple) to Pepipost’s server.

Just because of one reason -> network latency.We have deployed our SMTP servers globally at multiple locations. We can serve your email sending requests from the nearest location to reduce network latency.

Currently, our servers are located in Delaware, NY, Frankfurt, Bengaluru, Singapore, Mumbai and more are coming.
