What good email footers actually do

The email footer is one of the strangest small design objects in modern marketing. It sits at the bottom of every message, contains the least polished copy in the entire program, is almost never rewritten, and is legally load-bearing. It is one of the few parts of an email a regulator will look at closely. It is also, if written well, one of the parts a subscriber remembers.

Almost every email program has a footer that came out of a template, was edited once at setup, and has not been touched since. This is a mistake. The footer is doing at least four jobs, and doing them all through a block of grey text that nobody has read all the way through since 2019.

The four jobs of a good footer

First, the footer says who you are. The physical postal address of the sender is required by CAN-SPAM in the United States, by GDPR-adjacent frameworks in Europe, by NDPR in Nigeria, and by every serious data protection regime. Skipping this is a legal risk, and framing it as an afterthought is a design tell.

Second, the footer offers a way out. The unsubscribe link is not optional and should never be hidden. The best footers make the unsubscribe link visible and unstressed — the size of the body text, in the same colour as everything else, no smaller and no lower-contrast. Trying to hide the link is a signal to inbox providers that the sender is behaving badly, and receivers now factor this signal into placement decisions.

Third, the footer answers "why am I getting this?" A single sentence naming the source of the subscription, and if possible the date, dramatically reduces the rate at which subscribers mark you as spam instead of unsubscribing. "You are receiving this because you signed up on our website in March 2024" is worth writing. Subscribers forget when and where they signed up, and reminding them is a courtesy that pays back in complaint rate.

Fourth, and most underused, the footer sets tone. The footer is the last thing a subscriber reads. The tone of it, more than the tone of the subject line, is what stays with them. A footer that reads like a legal notice makes the entire email feel corporate. A footer that reads like a human wrote it makes the entire email feel like the sender is a person.

What good ones look like

The best footer I read regularly is on a newsletter I have been subscribed to for years. It says the sender's name, their city and country, the sentence "You signed up at some point in the last few years — hi", and an unsubscribe link. That is the whole footer. Under a hundred words. It reads as though the sender wrote it, because they did.

The worst footers are three columns of social icons, six links to "resources," a copyright notice, an unsubscribe link buried under grey text at eight-point size, and a corporate address that has clearly been auto-inserted by the tool. These footers are worse than useless — they actively signal to receivers that the sender does not care about the medium.

Common mistakes

• Six social media icons in a row, three of which link to accounts that have been dormant for years.
• An unsubscribe link at ten-point grey text on a white background. This will fail accessibility checks and irritate subscribers into marking you as spam.
• A "view in browser" link at the top of the footer instead of the top of the email.
• A corporate address that is a PO box the subscriber cannot verify. This is legally compliant and reputationally suspect.
• A copyright notice with the wrong year, updated once every four years by whoever remembers.

The footer is what the subscriber sees last, and what stays. Redesign it as though the whole email will be judged by it, because sometimes it will be.

A twenty-minute redesign

Open your last send. Read the footer out loud. If any part of it sounds like it was written by a lawyer who was billing hourly, rewrite that part in your own voice. Cut anything that is not doing one of the four jobs above. Update the copyright year. Check the address. Make the unsubscribe link the same size and colour as the body text.

This is a twenty-minute job, and every email you send for the next several years will benefit. That is a genuinely good return on twenty minutes.
