Your sales and support teams live in two places: their inbox and their CRM. Every time they switch between the two, context is lost, records go unlogged, and deals slip through the cracks.
MTS Mail Pro eliminates that gap.
Instead of a dated, clunky email interface bolted onto the side of SuiteCRM, MTS Mail Pro gives you a fluid, modern experience that feels as natural as Gmail — while being deeply wired into your CRM data. Emails are read, sent, and imported without a single tab switch. Compose windows appear right on top of a Contact or Account record, recipient and relation pre-filled. One click turns an incoming email into a logged CRM record, linked to the right module and assigned to the right person.
The result: your team spends less time managing tools and more time closing deals.
For teams that take email seriously inside their CRM.
