Comparison
CodeTwo alternative from Germany — SignatureHub comparison
CodeTwo from Poland is strong on Exchange on-premises and Microsoft 365. SignatureHub is the better fit if you need German hosting, mix mailserver types, or want true MSP tenant management.
SignatureHub advantages
- Hosting in Germany vs. Poland
- Postfix, Plesk, sendmail native
- Usable without any mail server of your own: mail client straight to mx.signaturehub.de:2587 (STARTTLS) with per-employee credentials
- Tenant model with consolidated invoicing
- German DPA, German data protection authority
Frequently asked questions
- Do I need Microsoft 365 to use SignatureHub instead of CodeTwo?
- No. There are three ways to connect: Microsoft 365 via outbound and inbound connectors, your own mail server (Postfix, Plesk, Exchange on-premises) as a smarthost to mx.signaturehub.de:2587, or — with no mail server at all — the mail client pointed directly at the same endpoint using per-employee credentials.
- Does this work if our mailboxes are hosted at STRATO, IONOS or All-Inkl?
- Yes. Every employee gets their own SMTP credentials and enters mx.signaturehub.de, port 2587, STARTTLS as the outgoing mail server in Outlook, Apple Mail, iPhone, Android or Thunderbird. Incoming mail stays with the existing provider; only the sending path runs through SignatureHub. Credentials are bound to that employee's own addresses.
