Signature 365 from Symprex and Footer365 both add email signatures to Microsoft 365 mail server-side, both have an Outlook add-in, and both price in pounds with monthly plans you can cancel at any time. The difference is in what you can measure, how long your price is fixed, and how few people you can start with. Every Signature 365 fact here was read from Symprex's pricing page.

Signature 365 is a capable product, and moving is only worth it for something you will use. These are the differences that come up, each worked out from the two companies' own published terms.
Footer365 counts the clicks on your banners and leaves out the security scanners that open links to check them, so the figures are people. You can A/B test two banners and rotate several. Symprex's pricing page does not list click analytics.
Choose a 12, 24 or 36-month term and its price is fixed until it ends, with a further 5% off for two years and 10% off for three.
Like Signature 365, a Footer365 monthly subscription can be cancelled at any time, with no notice. It ends on the last day of the month in which you cancel, and nothing is invoiced after it.
Signature 365's published prices start at 10 users. Footer365 is sold from 1, with every feature, so a small team pays for the people it has.
On a yearly term, Footer365 costs less per user than Signature 365 at every number of users on Symprex's pricing page. The figures are in the table below.
Signature 365's trial is 14 days. Footer365's is 30, with every feature and no card, on your own mail.
Import the HTML of the signature you have. Footer365 converts the merge fields Symprex writes into its own and copies the images across, so you do not start again.

Per user per month, excluding VAT, on a yearly term, as each publishes it.
Both include banner campaigns in their one plan, so the two compare like for like. Footer365 bills the user mailboxes in your directory, never fewer than a term's committed seats, which are counted when the term starts; shared, room and equipment mailboxes are not counted.
Footer365's full curve, including its monthly prices and the discounts for two and three-year terms, is on the pricing page.
Signature 365 goes on signing everyone until you switch it off, so there is no gap in your signatures. The full checklist is in Switching from another signature service.
Take the HTML of each signature and import it; Footer365 converts Symprex's merge fields and copies the images. See Import a signature from another provider.
Try it while Signature 365 still signs everyone else. Take the pilot group out of Signature 365's rules if you can, or they see two signatures until you switch over.
Remove Signature 365's rules, connectors and add-in in one sitting, so nobody is signed twice.
Once mail has gone out with only the Footer365 signature for a few days.
Bring your signature with you, try it on your own mail for 30 days, and pay a price that is fixed for the whole term you choose.
