Startup Email Signature Generator
27 startup email signature designs with product link, app badges and a hiring or launch line
100% free. Runs entirely in your browser - your files and data never leave your device and nothing is uploaded to any server.
Icons are small hosted images with the network name as alt text, so they still read when images are blocked.
Mail clients can't read files from your PC - an image must live at a public https:// link. This makes an email-ready copy (cropped, under ~50 KB) for you to host.
Presets are common wording, not legal advice - check what your firm or regulator requires.
Upload a CSV or Excel file with Name, Title, Email (and optionally Phone, Mobile, Department, Photo URL, LinkedIn). You get one .htm signature per person in a ZIP, in the current design.

Checks
Images
- No images - the signature is text and tables only, which every client shows.
- Every image has width, height and alt text, so Gmail cannot stretch it and a blocked image still reads as text.
Before you use it
- Send a test email to yourself (and one to a Gmail and an Outlook address if you can) before using it for real.
- Open it on your phone - wide signatures scroll sideways on small screens; pick 480 px if yours does.
- View it with images blocked (Outlook desktop does this by default): the alt text and initials should still say who you are.
- Click every link - phone, email, website, social, button - from the received email, not the preview.
- Reply to that test email once, to check the signature does not duplicate or stack in a thread.
- Check it in dark mode on your phone; logos with transparent backgrounds can disappear on black.
Signatures for teams that change every quarter
A startup's details do not sit still. The title changes when you raise, the product link changes when you launch, the team doubles in a quarter and the tagline moves from "in beta" to "now on iOS". A startup email signature has to keep up without someone redesigning it each time. These 27 designs are made for founders and early teams: a clean name-and-role block, a product link, optional App Store and Google Play badges, and a promo line for whatever the company is pushing this month - a launch, a funding announcement or "We're hiring". Set it up once, export it for everyone from a spreadsheet, and change one line when the news changes. The code is table-based for Gmail and Outlook, and nothing you type leaves your browser.
How to use this tool
- Pick a startup designChoose a clean founder layout, or one with room for app badges and a promo line.
- Add the product and the newsPaste your product or download link, add app-store links if you have them, and write this month's promo line.
- Match your brandSet the brand colour, font and logo so every team member's signature looks the same.
- Export for the teamUpload a sheet of names and roles to get one signature per person, then share the install cards.
What belongs in a founder's signature
Founders send the emails that matter most - to investors, early customers and first hires - and those readers check the signature to see who they are talking to.
- Name and role: "Co-founder & CEO" is clearer than a playful title in an investor email.
- Company name and one product link - the app, the waitlist or the demo.
- A mobile number if you want customers and investors to reach you quickly.
- LinkedIn, plus X or GitHub if that is where your audience follows you.
- App Store and Google Play badges once the app is live.
One promo line, changed often
The promo strip is the most useful part of a startup signature. Use it for one message at a time: "We're live on Product Hunt today", "Raised our seed round - read the announcement", "Hiring a founding engineer". Every email the team sends that week carries the news, and next week you swap the line.
One message is read; a stack of badges, awards and links is skipped. If you have two things to say, pick the one that matters to the people you email most.
Rolling it out as the team grows
Early teams grow in bursts. Keep a spreadsheet of names, roles and emails, and export the signatures again whenever someone joins - everyone gets the same layout, and the company looks established from the first customer email. When the brand colour or logo changes after a rebrand, update it once and re-export the whole team.
App badges and links that keep working
Store badges are images, so they are hidden when a mail app blocks pictures; every badge here also carries a live text link so the store page is still one tap away. Point product links at a page you control, such as your own /download page, so old emails keep working after you change stores or app names.

Tips for better results
- Change the promo line when the news changes - weekly during a launch.
- Use a download or landing page you control instead of a raw store URL.
- Keep the founder title plain in investor email.
- Re-export the whole team after a rebrand instead of editing by hand.
Mistakes to avoid
- Stacking every badge, award and banner at once.
- Leaving "in beta" in the signature months after launch.
- App badges without text links, which vanish when images are blocked.
- Each new hire copying an old signature with someone else's details still in it.
Frequently asked questions
