When buyers inquire about Email signature software, AI engines consistently highlight CodeTwo as the leader in this category. With a visibility percentage of 62.5%, CodeTwo outshines other brands. WiseStamp and Exclaimer also feature prominently in AI recommendations, showcasing their credibility and strong presence in the market.
The dominance of CodeTwo and other top brands in these rankings is mainly driven by sources like syncsignature.com, wisestamp.com, and codetwo.com.

For a buyer evaluating Email signature software, this ranking is a helpful guide.

At a glance
What we observed in this category
CodeTwo and WiseStamp share the top position with identical visibility scores of 62.5% and citation rates of 75.0%, giving them a composite score of 66.2 each. Exclaimer sits just behind at 62.5% visibility but only 50.0% citation, dropping its composite to 58.8. The gap that matters most is between rank 3 and rank 4: Bybrand scores just 12.5% on both metrics, meaning the top three brands collectively occupy a tier that the remaining 17 brands in the category cannot reach.
MySignature shows a clear divergence between visibility and citation: it appears in 12.5% of AI responses but receives zero citations, indicating Google AI Mode names it without linking to it as a trusted source. Canva Email Signatures and Letsignit show the reverse pattern, both scoring 0.0% visibility but 12.5% citation, meaning AI cites their domains without surfacing them as named recommendations. This split reveals that being named and being cited are meaningfully different signals in this category.
The top cited sources list includes syncsignature.com at the top position, ahead of wisestamp.com and codetwo.com, even though SyncSignature does not appear in the ranked brand visibility table. Review platforms g2.com and community forum reddit.com both appear in the cited sources list, confirming that Google AI Mode anchors responses in third-party validation content alongside direct brand domains. YouTube also features, suggesting video content is part of the sourcing mix for this category.

How to read this AEO 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. More on visibility →
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. More on citation rate →
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. How AI engines pick sources →
AEO 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 90 days and refresh this page automatically. How AI search ranking works →
