"The new CompleteSMS add-on for Gmail offers a seamless experience that works on your existing framework and allows for more immediate results with SMS. Users will have record of sent messages within their sent folder and have their replies show up in their Gmail inbox, too. Installation is simple, with no developer needed, and is compatible with the Gmail phone app, as well. The end result is simpler business SMS at your fingertips."

The add-on will enable users to access existing Gmail contacts and groups, add multiple signature templates that can also be used as message templates, schedule messages and more. The add-on is now available via the Google Workspace Marketplace.

Current CompleteSMS account holders can immediately start sending messages through the add-on once installed. New customers can start a free trial, after installation, through the add-on.
