What it is
Signature 365 is a cloud-based email signature service for Microsoft 365 and Office 365. A central dashboard lets organizations create and update signatures, assign versions by department or individual, and manage marketing campaigns and legal disclaimers. Templates can include branding, directory contact details, headshots, social links, banners, calls to action, and disclaimers. Signatures can be deployed client-side, server-side, or using both approaches. Symprex says signatures can be added to email sent from any client or device, with sent items updated, and that it does not access email content. An Outlook add-in can be deployed through the Microsoft 365 admin center, and signatures can also be added in Outlook on mobile devices. Campaign analytics track interactions and report on traffic, conversions, and sales opportunities. The service supports directory sync and automatic updates. Symprex describes its customers as businesses with 50 to 5,000 users, and says its largest customers manage more than 80,000 users. Signature 365 is paid and offers a 14-day trial with no commitment or credit card. Technical support is included, with email and phone support stated to be available five days a week.
