Mistake: stuffing the first email with links, images, and a signature banner
A cold first-touch with a calendar link, a tracked URL, an image signature, and social icons trips multiple content filters at once. It looks like marketing because it is.

The fix: first email = plain text, zero links, zero images, a one-line text signature. Save the Calendly link for after they reply. Most senders let you set a stripped signature per campaign — use it.

Pros / Cons of plain-text first touch:
— Pro: clears content filters, lands in primary
— Pro: reads like a real person typed it
— Con: no click data on step one
— Con: prospects must reply to get the link (that's a feature)

Verdict: 4.5/5. Every element you add to a cold email is a reason to filter it.

Who it's for: anyone whose first email has a banner signature and a booking link.
