How do I use TATA COMMUNICATIONS DIGO Email to create targeted marketing, customer service emails and alerts?

You can develop email as an element of your omnichannel campaigns, running in conjunction with ‘Engage’ our outbound marketing platform.

How are emails delivered?

Emails are delivered quickly and accurately. Tata Communications DIGO Email API makes it easy to manage and control your customer email programs.

How do emails reach my customers?

You get your email messages to your customers using our message transfer agent (MTA) for the best email delivery performance, including email address validation, queue management and throttle risk detection.


It is important that your customers know that it is you who is sending them emails. Apply email sender authentication protocols, reverse DNS, and dedicated IP addresses to provide assurance to your customers that they are receiving genuine messages from you.


Whether you are sending a few hundred emails, or several thousand, you can be sure that the same approach is applied to email delivery, security and tracking.
