Email Signature Management for Google Workspace

01

The problem, precisely

A 40-person company sends thousands of external emails a week, and every one carries a signature that is either on-brand or improvised. Left to individuals you get eleven fonts, four old logos, two ex-employees' job titles and one Comic Sans. Central management means: one template, everyone's real details, updated everywhere when anything changes.

Your three options in Google Workspace

• ✓Gmail's built-in 'Append footer', a compliance feature, not a signature manager. Rich text only, no per-person fields, OU-level granularity, appended invisibly below the quoted thread. Fine for a legal disclaimer; wrong for signatures.
• ✓Marketplace apps with Gmail API write access, signatures written directly into each user's Gmail settings after domain-wide admin consent. Zero-touch, but the vendor holds restricted Gmail scopes and an annual Google security assessment.
• ✓Client-side deployment (Sincerely's approach), signatures generated centrally from your directory, installed via a Chrome extension or personal install links, kept current by automatic sync. No restricted scopes, nothing touches mail flow, and you can see exactly who's installed what.

03

What good management actually requires

• ✓The roster comes from Google, nobody maintains a spreadsheet of staff.
• ✓Locked fields: brand controls the design; each person edits only their own details.
• ✓Targeting by organisational unit, because that's how your company is already structured.
• ✓A deployment dashboard: who's current, who's stale, who never installed.
• ✓Leavers deprovisioned automatically when they leave the directory.
