Simple Mail Transfer Protocol

SMTP (Simple Mail Transfer Protocol) is a protocol that allows you to send, receive, and relay email. Gmail, for example, has preset SMTP servers, but you may modify them to custom ones, such as SMTP Servers. This will send your emails through SMTP server's secure and reliable servers which might be useful if you need to send a large number of emails and ensure that they get in the inbox.

Say goodbye to email deliverability issues.

SMTP servers are a convenient way to deliver email, but an email API is much more efficient. APIs can process requests more faster than a traditional SMTP server, which is important for those sending millions of emails.

Our SMTP server may be fully integrated into your CMS, CRM

Because email distribution via an SMTP server lacks a built-in security layer, it's best to set up a secure SMTP server and ensure that your emails are encrypted and not visible to the public. Our SMTP server may be fully integrated into your CMS, CRM, or other system, allowing you to send e-mails to your customers directly from your website. We provide thorough API documentation, and you'll find all the personal settings you need for the SMTP server in your SMTP service account.
