SMTP/API section

There are two ways in which you can connect your application with ZeptoMail — SMTP or API. The Simple Mail Transfer Protocol (SMTP) is a set of rules that govern how emails are transferred over the internet. The mail transfer occurs using commands that are specific to the SMTP protocol. While the Application Programming Interface (API) acts as an intermediary between applications allowing them to borrow specific functionality (email-sending, navigational feature, payment methods etc.) from one another. 

ZeptoMail offers both SMTP and API for email-sending. You can pick either of the two based on your needs. Here's a quick comparison guide to help you choose between them.

Once you pick the desired method, you should obtain the credentials required to use them. This is available within the Mail Agent section and is unique to each Mail Agent. This helps segmenting email-sending based on your needs. 

Obtaining credentials

1. Choose the Mail Agent that you wish to connect with your ZeptoMail account.
2. Navigate to the SMTP/API section.
   1. SMTP tab - Provides the SMTP credentials required to configure SMTP with the application.
   2. API tab - Contains the API key and relevant details necessary to connect using API.

Sample code

Both SMTP and API section offer a list of sample codes in various languages, on the right. You can copy-paste the relevant code directly to your application.
