Letsignit vs Signature 365 (2026): which should you pick?

Pick Letsignit if

• Fits if your company is on Microsoft 365 or Google Workspace and wants signatures set with no work from staff
• Works for marketing teams that A/B test banners in employee email

Look elsewhere if

• Not for you if you want to pay monthly, as plans are annual subscriptions only
• Skip it if you want a free plan, because there's only a trial on request with no length stated
• Pricey if you need SSO, SCIM provisioning or on-premises deployment, which are Enterprise at a price you ask for
• Watch out: Slides, the PowerPoint product, is $2 a user extra or part of Platform at $3.20
• Watch out: chat support runs weekdays 8am to 11pm CET, and premium support is Enterprise only

Pick Signature 365 if

• Fits if you run Microsoft 365 for 10 or more people
• Works for companies that want the same signature and campaign banner on all mail

Look elsewhere if

• Skip it if you use Google Workspace, since it targets Microsoft 365 only
• Not for you if you have fewer than 10 users, as the minimum is 10
• Watch out: licenses count every user and shared mailbox, signature or not
• Watch out: it is not covered by the 30-day money-back guarantee on Symprex's other software
• Watch out: cancelling ends the subscription at period end and the data is deleted
