## Description

icomm SMTP sends WordPress mail through a mail provider SMTP server instead of the
server PHP mail() function. This WordPress.org edition includes custom SMTP, a send
log, sender name, a weekly report, and a test email. There is no license key.

#### What you get

 * **Custom SMTP** with host, port, encryption, username, and password from your
   provider (SendGrid, Amazon SES, corporate server, and similar).
 * **Sender (From)** email and display name, with optional force options.
 * **Send log** of successes and failures (date, recipient, subject, and a filtered
   error excerpt). The full message body is not stored.
 * **Test email** from wp-admin.
 * **Weekly report** by email from the send log (optional).

Microsoft 365 / Outlook and Google / Gmail connections (including OAuth) are available
in the PRO version at [icomm.market](https://icomm.market/icomm-wp-mail-smtp-en/).
This WordPress.org package is complete for custom SMTP.
