Common questions

What makes an email signature actually good?

It's short, it's readable on a phone, and every line earns its place. The best signatures identify the sender, provide one clear way to respond, and get out of the way. Anything else — banners, quotes, three social icons — should be justified case by case.

How many lines should an email signature be?

Four to six lines is the sweet spot. Anything beyond that starts to look like a business card designed by committee. If you need more, split into a main block and a small footnote for legal or disclaimer text.

Should I use images or icons in my email signature?

One small avatar or company logo is fine. Rows of icons for every social network hurt readability and often break in dark mode. Wren renders social icons as inline SVG so they work everywhere.
