What we observed in this categoryauto-generated
CodeTwo leads the email signature management software category with a visibility score of 37.5% and a composite score of 45.0, more than double Exclaimer's composite of 21.2. The gap between first and second place is significant because the average category visibility is only 3.8%, meaning CodeTwo is performing roughly ten times above the category mean. Exclaimer sits in a clear second position, but ranks three through ten drop sharply, with Opensense at 12.5% visibility and every other tracked brand scoring zero on both visibility and citations.
A notable divergence appears between visibility and citation rates. CodeTwo's citation rate of 62.5% substantially exceeds its 37.5% visibility, suggesting AI is actively linking to its domain as a trusted source, not just mentioning the brand. Exclaimer shows the opposite pattern, with visibility at 25.0% but citations at only 12.5%. WiseStamp presents the starkest anomaly, recording zero visibility yet a 12.5% citation rate, meaning AI is referencing its content without naming the brand in responses. Opensense has 12.5% visibility but zero citations.
Google AI Mode is the dominant engine across all ranked brands in this category, with every brand listing it as their top engine. The top cited sources include g2.com and reddit.com alongside codetwo.com and exclaimer.com directly, indicating AI is anchoring on third-party review and community platforms as well as vendor-owned content. The presence of mail-signatures.com, syncsignature.com, and anniemargaritayang.com in the cited sources list points to niche and individual-creator content carrying meaningful weight in AI responses for this category.

Sources AI engines trust in this category
Across the 8 buyer-intent queries we ran on email signature management software, these are the domains Google AI Mode cited most often. If you're not on this list — or if your competitors are — that's a concrete PR / linkbuilding target.
How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer.
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence — different from being named.
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps.
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically.
