How CodeTwo works
CodeTwo offers both on-premise and cloud-based email signature solutions. Their cloud product, CodeTwo Email Signatures 365, uses server-side signature injection through Exchange Online transport rules. Emails pass through CodeTwo's processing before being delivered.
CodeTwo also has an on-premise product that runs on your own Exchange server. While this gives you more control, it adds infrastructure to maintain and update.
MailTail is purely client-side. The Outlook add-in applies signatures directly in the compose window. No transport rules, no server-side processing, and no infrastructure to manage. Your emails go straight from Outlook to the recipient.
CodeTwo pricing explained
CodeTwo uses volume-based pricing in USD. The per-user cost varies depending on how many users you have, with different price breaks at different tiers. You need to use their calculator or contact sales to get an exact quote for your team size.
MailTail is a flat £0.57/user/month regardless of team size. Whether you have 10 users or 500, the price per user stays the same. Annual billing is available at £5.81/user/year, which works out to a 15% discount. No tiers, no calculator, no sales calls.
Server-side vs client-side signatures
CodeTwo's server-side approach means signatures are added after you hit send. You do not see the signature while composing, which can cause formatting surprises. It also means your email content is processed by a third-party service before delivery.
MailTail's client-side approach means you see your signature in the compose window as you type. What you see is what the recipient gets. Your email content never passes through our servers, which simplifies compliance and data residency requirements.
Who is CodeTwo built for?
CodeTwo is a well-established product with a strong reputation, particularly for organisations that need on-premise solutions or have complex multi-platform requirements. Their product supports a wide range of deployment scenarios.
MailTail is built for Microsoft 365 teams who want a simpler solution. If you are fully in the cloud on Microsoft 365 and want signatures deployed in minutes without configuring transport rules or managing infrastructure, MailTail is the lighter-weight option.
