Similar to transactional SMS, transactional emails serve the purpose of updating your customers on confirmations. This can be about the purchase of a product, sending an e-ticket, password resets, login ID confirmations and OTP verifications. The fact that these are vital pieces of information makes them a high click rate.
Transactional email is triggered by events or preferences of a customer when using a service and these emails are particularly useful for a company when they are trying to reach out to inactive customers.

After creating your account with MSG91, to get started with emails, get your domain added and fully configured. Then Set up SMTP or integrate with API to start sending transactional emails. 

Promotional emails majorly contain commercial content or message that has a commercial value & are generally sent to a large number of groups for generating the leads. Transactional emails are triggered by a user action on a website or mobile app. Some common examples of transactional emails include password resets, shipping confirmations, invoices, account notifications, and welcome emails. These emails are typically sent programmatically through an email API or SMTP server. P.S- We only provide transactional email services that can be integrated via API

A transactional email is an automatically generated email exchanged between a sender and a recipient.
Transactional emails are not sent across in bulk, as it entirely depends on an individual and the time between the person-to-organisation communication. The email is also personalised to communicate directly with that individual.

Businesses do not require to take consent from the individual they are sending a transactional email to, as the email is only generated after the individual has initiated a request. This is also typically done to validate any form of information sent across.

For example, when you request a password reset for an application after selecting “Reset Password”, you expect to quickly set a new password and log in to your account. Here, these applications send the instructions through an automated email. Following the instructions in the
transactional email, you can reset your password and continue using the software application.

MSG91s intuitive API lets you create emails that are auto-generated through programming and sent out to your customers. Here are some quick tips on creating clear and concise pieces of information for transactional emails.

  • Is your email action-oriented? If so, based on what the user has requested, create a template that answers or confirms those queries
  • Structure and position the content strategically so that the customer understands the content at a quick glance.
  • It’s always good to break down your information into a step-by-step flow. Keep the main information in the subject and then details of the content in the main body.
  • Keep the email simple and do not use Bold letters and exclamation marks excessively.
  • Test different assumptions and send emails to test subjects before finalising the main content.
  • Make use of our list of email templates if you require some guidance on how to best get your information across.
