Transactional email with usage-based billing

Zoho ZeptoMail for WordPress connects a self-hosted WordPress site to a ZeptoMail account for notifications such as password resets, welcome emails, and order confirmations. The add-on and service are free to get started with, and new accounts include 10,000 free emails on sign-up. You can buy additional credits when you need to send more. The pay-as-you-go plan bases payment on usage, subject to the service’s Usage Policy.

Route WordPress mail through the API

The add-on customizes WordPress’s PHPMailer library and handles the send-mail action through wp_mail(). Site notifications can use the configured ZeptoMail connection without changing options at each occurrence. This setup may help when wp_mail() is not working or notification emails reach spam. ZeptoMail recommends authorized sending because unauthenticated setups may be misused and harm a domain or website’s reputation.

Configure sender and message defaults

Choose the hosted region where your Zoho Account data resides, then set the default email format. The available settings also include the show name, outgoing From email address, Send Mail token for the ZeptoMail Agent, and the number of logs to retain before older entries are deleted. Messages are sent through the configured Agent and its associated domain.

Test the connection and set up the extension

Use the Test Email page to enter a From address, recipient, subject, and message content, then send a test from your site settings. Before setup, prepare a ZeptoMail account and a self-hosted WordPress website running PHP 5.6 or later. Enter the hosted region, sender details, email format, Send Mail token, and log limit in the add-on settings, then save and test the configuration.
