Template previews show the signature that actually sends
A connector's signature is now baked into template drafts when they're created, so the preview matches the delivered email exactly — with a safeguard against the signature ever doubling up.
What you see in a template preview should be exactly what your recipient gets. For template campaigns, the signature was the one part that could differ between the two — the preview might show one thing and the delivered email another.
What was happening
A connector's signature was only attached to the email at the moment it was sent, not when the draft was created. For template campaigns, that meant the preview you reviewed was built before the signature was in place, so it could show something different from the final email that landed in your recipient's inbox. The preview was an honest reflection of the draft as it stood — it just did not yet include the part that gets added on the way out the door. This affected template campaigns specifically, where the draft is generated ahead of time and you preview it before it goes out, so the window between what you reviewed and what was sent was exactly where the signature slipped in unseen. The gap was easy to miss precisely because it only appeared at the very end of the flow: everything you reviewed looked right, and the difference only existed in the version that actually shipped.
What we fixed
The connector's signature is now baked into the template draft at the time the draft is created, rather than being bolted on at send time. Because the signature is part of the draft from the start, the template preview and the delivered email are built from the same content and show the exact same signature. We also added a safeguard so the signature cannot be applied twice — there is no risk that moving it earlier in the process causes it to appear once in the draft and again at send, leaving a duplicated signature at the bottom of the email.
Why it matters
Previews are only useful if you can trust them. Now what you proof is what your recipient receives, signature included — so you can review a template once, see precisely how it will look when it arrives, and launch without wondering whether the sent version will match. Your signature carries real weight in cold outreach — it is where your name, role, and contact details live, and a clean, consistent sign-off is part of looking legitimate to someone hearing from you for the first time. Having it render identically in preview and in the inbox means there are no surprises in the part of the email that vouches for who you are, and it rules out the embarrassing failure mode of a signature showing up twice in a real send.
