CodeTwo Email Signatures 365 is an established cloud service for signatures in Microsoft 365, licensed per user per year. SignetMail is an alternative for companies with up to 50 users who don't want to pay per seat, for those who run Google Workspace as well as Microsoft 365, and for those who want the server on their side. If you need 24/7 phone support and a product with a long track record, CodeTwo is the safer choice.

What does it cost per year?
CodeTwo prices step down with volume. For 30 users the upper bound at €1.22 per user per month is about €440 a year (30 × 1.22 × 12); the real amount can be lower because the price falls for more licenses. SignetMail is free at 30 users.

When is SignetMail a good CodeTwo alternative?
- You have up to 50 users and don't want to pay per seat.
- You also run Google Workspace. One tool manages signatures in Outlook and Gmail.
- Data must stay with you. You install SignetMail on your own server; the directory and signatures stay in your environment.
- You want an EU vendor you can reach in your own time zone.
When should you stay with CodeTwo?
- If you need 24/7 support by e-mail and phone.
- If you want a product with a long history and many references (SignetMail is a young product).
- If you don't want to maintain anything and it matters that the vendor is a large, established company.
How do you switch from CodeTwo to SignetMail?
- Install SignetMail with Docker or the Windows installer and connect Entra ID or Google Workspace.
- Bring your template over. Import the HTML of your current signature and replace the details with placeholders for name, title and phone.
- Set up rules for departments or groups, as you had them in CodeTwo.
- Test with a pilot group. Assign the Outlook add-in to a few people first and check their signatures.
- Turn off CodeTwo. Remove their rule or add-in so the signature is not added twice.
