Which should you choose?
Choose Exclaimer if
- You use Microsoft 365 or Exchange, or a mix of Microsoft and Google.
- You need the signature added server-side to mail from any device.
- You need enterprise controls such as legal disclaimers at scale, delegated administration and vendor certifications for procurement.
- You have well over 100 mailboxes and want a vendor with a large partner network.
Choose SigDeploy if
- You run Google Workspace and want a tool built only for it.
- You want signatures written straight into Gmail, with no mail routing to set up or maintain.
- You want your Google organizational units to decide who gets which signature.
- You prefer one flat monthly price over per-user math, with no sales call.
Frequently asked questions
Is SigDeploy an Exclaimer alternative for Google Workspace?
Yes, if you only use Google Workspace. SigDeploy covers the core job of designing, assigning and deploying Gmail signatures, plus banner campaigns, at a flat monthly price. It does not support Microsoft 365 or Exchange.
How do SigDeploy and Exclaimer differ in how signatures reach the inbox?
Exclaimer inserts signatures server-side as mail is sent. SigDeploy writes the signature into each person's Gmail signature setting through Google's API, so it appears when they compose in Gmail and nothing sits in the mail flow.
Which costs less?
It depends on headcount. Per-user tools can cost less for very small teams. At 100 employees SigDeploy is $25 a month, while per-user pricing in the roughly $1 to $3.50 range works out to about $100 to $350 a month.
