Yes, you can connect your existing email accounts to DeskPRO. Users will still email your existing support@ address, but each new issue they raise will be converted to a ticket within DeskPRO. Your agents can reply to tickets through the easy-to-use, efficient DeskPRO web interface, or by email.
Because there's a single ticket record for each issue, DeskPRO makes it easy to keep track of the conversation without inbox overload.
You don't have to limit it to your support@ address. You can connect your sales@, jobs@ etc. addresses too, and link them to different departments within DeskPRO.
For DeskPRO Cloud, see Custom email address configuration in the admin manual for more details.
For DeskPRO On-Premise, see On-Premise email configuration in the sysadmin manual.
