Email Signatures for Nonprofits

Your team sends thousands of emails to donors, partners, and supporters. Turn every one of them into a chance to advance your mission with a donate button, a campaign link, or a call to volunteer.

Create Your Nonprofit Signature

Nonprofits work with tight budgets and big goals, and email is one of the most cost-effective channels you have. Every message your staff and volunteers send is a free, repeated touchpoint with someone who already cares about your cause. htmlsig helps you make the most of it by turning each signature into a small but persistent call to action. Add a donate button, feature your latest campaign, and point supporters to events and volunteer signups. Set one branded template, roll it out to everyone, and your mission shows up consistently in every inbox.

The Email Signature Gaps Nonprofits Face

Thousands of staff and volunteer emails go out every month with no ask and no link to give.
Staff and volunteers use mismatched logos, fonts, and layouts, weakening your brand.
New campaigns and events launch but never make it into the signatures your team is already sending.
Updating a donate link or campaign banner means chasing down every staff member and volunteer one by one.
