MailSignatures.io vs Newoldstamp (2026): which should you pick?

Pick MailSignatures.io if

• Fits if you run Google Workspace for a team of 5 to 50
• Works for one person with a personal Gmail account who wants a signature synced

Look elsewhere if

• Skip it if you use Outlook or Microsoft 365, which the pages do not cover
• Watch out: prices shown are annual, and only Solo's $4 monthly rate is stated
• Tight if you want support, since priority support starts at Business, 6 to 20 users
• Watch out: Solo has no trial, only a free preview before you pay to sync

Pick Newoldstamp if

• Fits if you need a handful of branded signatures and are happy to pay for a year up front
• Works for teams on Google Workspace, Microsoft 365 or Exchange that schedule banners by department

Look elsewhere if

• Not for you if you want to pay monthly, as the pricing page only shows yearly prices
• Tight if you're staying free, because you get simple templates and Newoldstamp branding on the signature
• Watch out: during the 7-day trial you can build signatures but not use them until you pay
• Watch out: signatures stop working when the subscription expires or the account is deleted
• Watch out: the slider stops at 200 signatures, and beyond that the price is a quote from sales

MailSignatures.io
