A clean sign-off matters. Two of them stacked at the bottom of the same email looks like a mistake — and in cold outreach, looking like a mistake is one of the fastest ways to lose a prospect before they reach your ask. We fixed an issue where AI Autopilot emails could leave the outbox with a duplicate signature.
What happened
When the AI drafted an email for an Autopilot campaign, it sometimes composed its own closing sign-off as part of the draft — a natural conclusion to the message it wrote. Separately, your sender's connector signature was then appended as well, because the signature engine runs on every outbound email regardless of what the AI included in the body.
The result was two signatures stacked at the bottom of the same email: the AI's closing, followed by your configured sender signature. Recipients saw both. For a prospect opening a cold email, a doubled sign-off reads as an obvious formatting error — the kind of thing that signals an automated system that isn't quite under control, which is the exact opposite of the impression you're trying to make.
What's fixed
The AI no longer writes its own sign-off as part of the draft. Your connector signature is now the single source of the closing on every Autopilot email, so every message leaves the outbox with exactly one signature — the one configured on the sending account, honoring your per-campaign Append signature setting introduced alongside this fix.
We verified the change on live sends: drafted emails close with a single signature, and the per-campaign toggle controls whether that signature is included at all. No second signature appears regardless of the AI's drafting style or the sequence step.
Why it matters for cold outreach credibility
Cold outreach is judged in seconds. A prospect who opens your email is deciding within the first few lines whether to keep reading. A doubled signature near the bottom doesn't kill the read at line one — but it does register as "something is off here" for anyone who scrolls that far, and it undercuts the care and precision that good cold outreach signals.
More broadly, every formatting artifact that marks an email as automated works against you. The goal of AI Autopilot is for the AI to write emails that feel like they came from a real person with a real interest in the prospect. A sign-off that appears twice is a tell that breaks that framing. Removing it keeps the email feeling intentional and human.
What you should do
Nothing. Your AI Autopilot emails go out with one clean signature automatically. If you want to control whether the signature appears at all for a specific campaign — useful for short cold openers where a lean format works better — you can now do that per campaign using the Append signature toggle in the Sender Accounts picker. The connector default applies wherever you haven't set a campaign-level preference.
