Email signature

A 40-person company sends roughly 200,000 emails a year. The signature is the cheapest and most repeated placement a win will ever get.

Why this one is worth the effort

Every other channel reaches people who chose to look at your marketing. The signature reaches people already in a working conversation with you — the prospect mid-evaluation, the procurement officer, the candidate deciding whether to take the second interview. It is also the only placement where the reader sees the claim ten or twenty times over a deal cycle.

Run it for the licence period and then take it down. A signature badge from three cycles ago quietly signals that the last good thing happened three years ago.

What to add

One line or one small badge. Not both, and never a stack. Choose by how well known the program is to the person receiving the mail.

SituationUse
The program is famous in your buyer’s industryThe badge image — recognition is instant and needs no words
The program is credible but not famousA text line naming the award, the category and the year
You have more than one current winOne text line for the strongest; the rest live on your awards page
Regulated industry, plain-text mail policyA text line, always. Images are stripped or blocked
  • Keep the badge under 120px wide and under 20KB — signature images are downloaded on every send.
  • Link it to your awards page, with tracking parameters so you can see whether anyone clicks.
  • Put it below your contact details, not above your name.
  • Give the image alt text, because a large share of recipients block images by default.

Rolling it out across the company

  1. 1.

    Decide the exact line centrally

    One approved wording and one approved asset. If each team writes their own, you get five versions of the award’s name and none of them match the organiser’s.

  2. 2.

    Push it, do not ask for it

    Google Workspace and Microsoft 365 both support administrator-managed signatures or an append rule. A request to 40 people gets you 12 signatures and 6 broken ones.

  3. 3.

    Test on mobile, dark mode and plain text

    Send to yourself on iOS Mail, Gmail Android, Outlook desktop and one webmail client. A transparent-background badge disappears entirely in dark mode — use the dark variant or a solid background.

  4. 4.

    Set the removal date in the same change ticket

    Signature changes are administered, so removal can be scheduled the day it goes live.

Never add the badge to transactional or system email — invoices, password resets, alerts. Marketing furniture on a billing email reads as spam and can trip filters.

The text variant survives every client, every dark mode and every image blocker. If you are choosing under time pressure, choose the text.

Common mistakes

  • Three badges stacked under the contact block.

    One. The rest belong on the awards page.

  • A 600px-wide banner that dwarfs the actual message.

    Under 120px wide, below the contact details.

  • A transparent PNG that vanishes for every dark-mode reader.

    The dark variant, or a badge with a solid background.

  • Leaving it in place for years after the licence expired.

    A scheduled removal date, set the same day it goes live.

  • Everyone rolling their own version.

    One centrally administered signature, pushed by IT.

  • Adding it to invoices and password resets.

    Human correspondence only.
