Zoho has unveiled their new transactional email service, TransMail.
Transactional emails are those which are sent automatically based on user interactions with your website or app, such as receipts, password resets, or tracking information. Deliverability needs to be high for these types of the email so it is common to use a separate service to send them (with a separate IP and even using a subdomain or different domain altogether).
Other popular Transactional Email services include Amazon SES, Mailgun, and Postmark. Recently Mailerlite released their transactional email service.
