Simple Email Signature: priced by signatures, not seats

Simple Email Signature is an email signature generator I build and run at simplemailsignature.com. You fill in a name, a role, a logo, a headshot and a brand color, watch the signature build as you type, and export clean HTML that holds up in Gmail, Outlook and Apple Mail. What makes it different is the pricing: you pay for how many signatures you need, not how many seats you fill.

What's wrong with how signature tools are priced?

Premium email signature tools license one logo to one account. That's fine if you run a single company. It gets quietly expensive the moment you don't.

Run three brands and you pay three times. At the category leader, that's $180 a year for what is really one person's signature in three coats of paint. Add client work, side projects, or a team where everyone needs their own signature, and the per-account cost compounds fast.

None of that is a better signature. It's the same signature, billed again for every logo on it.

I ran into it myself. I manage a few personal brands and a few software products, each with its own support address, and none of the free signature generators let me keep a good-looking signature across all of them. Most can't even edit a signature you already made; you start over every time.

So I built one for myself. Now I also make a matching signature for clients whenever I redesign their website or build their brand, so they look the same on the web and in the inbox. Once it worked for me, it was clear it would help any business with several brands, or a team that wants matching signatures it can update in bulk: swapping the call to action on everyone's signature for a limited-time promotion, for example.

How is Simple Email Signature priced?

One account, one login, up to 500 signatures, starting at $39 a year. There's no five-user minimum to get in the door, and no seat minimum at all.

There are eight tiers, sized by how many signatures you need. A free tier builds one signature with a small attribution tag. Every paid tier removes the tag and comes with unlimited re-edits.

• Free: one signature, with the attribution tag
• Solo: $39 a year, one signature
• Studio: $79 a year, three signatures, with sync groups
• Team: $119 a year, five signatures, with sync groups and no seat minimum

Larger plans cover 25 to 500 signatures; their prices are on the pricing page.

What does the builder do?

• It renders live. The signature updates as you type, so you see exactly what you'll send.
• It exports HTML that survives real inboxes. Gmail, Outlook and Apple Mail each treat email HTML their own way. The export is built to come through all three.
• It has sync groups. A team can share a logo, a brand color and a call to action while each person keeps their own name, title and phone number. Change a shared field once and every signature in the group updates together.
• It has animated logo styles, for people who want their mark to move a little.

Sync groups are the feature I'd point to if someone asked why this isn't just another form that spits out a table. The hard part of signatures on a team isn't making the first one. It's keeping all of them consistent after the logo changes.

What did building it teach me?

The main idea in this product is the pricing, not the code. Pricing by seat assumes one person, one brand. Pricing by signature fits the people I was building for: owners with several brands, and small teams who don't want to pay for five seats to get one signature each.

The other half is the export. A signature builder is only as good as what arrives in the recipient's inbox, so "it looks right in the builder" was never the finish line. Surviving Gmail, Outlook and Apple Mail was.

The hardest part was dark mode. Gmail and Apple Mail invert colors differently, so no single set of colors looks exactly the same in both. What I settled on is a plate: a white rounded box behind the logo. It looks intentional in light and dark mode alike, and it saves making a separate logo for each mode, which is hard for any signature to get right once a mail client starts inverting colors.

If you're paying for the same signature more than once because you run more than one brand, it's built for you. Build your first one free at simplemailsignature.com.
