Help & troubleshooting.
Installing a signature is something you do in your own email app’s settings. This tool never connects to your email account. Pick your app below, then check the fixes if something looks off.
Before you start
- Finish your signature in the builder and open the Export tab.
- If you uploaded a logo or photo, click Copy details & download image. The copied signature doesn’t include the image; you’ll insert the downloaded file in your email app.
- Paste into your email app’s signature settings on a computer. Desktop and web settings usually keep formatting better than phone apps.
- Send a test email to yourself and to an address that uses a different email app. Check links, spacing and the image, then reply and forward it once.
The preview in the builder is an approximation. Email apps render HTML differently, so a real test email is the only reliable check.
Troubleshooting
My logo or photo is missing
If you used Upload, the image lives only in your browser, so it isn’t part of what you copy. Insert the downloaded image through your email app’s signature editor: see the image steps for Gmail,Outlook or Apple Mail. If you used an Image URL, check that the address opens in a private browser window without signing in.
Recipients see a blank box or “download pictures” message
Many email apps hide remote images until the reader allows them, or block them by company policy. That’s the recipient’s setting and can’t be overridden. Keep your key details as text (this tool never turns text into an image), and add alt text in the Images tab so a blocked image still says something useful.
Spacing or fonts changed after pasting
Some editors add their own spacing or swap fonts. Try the Compact spacing option, choose Arial or Verdana, and paste into an empty signature box. In Apple Mail, turn off “Always match my default message font”. If one app keeps changing things, copy again and paste directly into that app’s signature settings rather than via another document.
“Signature is too long” or it won’t save
Gmail documents a 10,000-character limit and counts images toward it. The Export tab shows the HTML size as a conservative estimate. Remove optional lines or links, shorten the address, or use a smaller image. If you inserted a large image in Gmail, resize it or use the “Exact size” download.
The Copy button doesn’t work
Some browsers or company policies block clipboard access. When that happens the Export tab shows a Select signature button: click it, then press Ctrl+C (Windows) or ⌘+C (Mac). You can also download the HTML file, open it in your browser, select the signature and copy it.
A link or detail still points to an old person or role
Signatures are copies: changing them here doesn’t update ones already installed or already sent. Update the details, copy again and replace the signature in each email app and on each device. If you reused a teammate’s profile, check every field, including the booking link and social links. Test every link with Test links in the preview (in the preview’s ••• menu).
It looks different in dark mode
Dark mode varies by app: some keep your email light (like Gmail on the web), some adjust the colors (like Outlook and the Gmail apps: dark text turns light and light backgrounds turn dark), and a few invert everything. A signature can’t force any of these; the reader’s app decides. The builder’s Dark preview is a simulation, not a real test. Signatures have a transparent background by default, so they blend in with the rest of your email; choose Background: White under Style → Advanced settings if you’d rather keep a white panel (it can show as a white box in dark mode). Images are never recolored: logos with transparent backgrounds and dark artwork can disappear on dark backgrounds, so a logo with its own background (or a light outline) is safer. Check a real email in dark mode on the devices you use most.
I send from more than one address
Most apps let you set a signature per address or account. Gmail lets you pick a signature for each “Send mail as” address; Outlook and Apple Mail set signatures per account. Create one signature per address here (a profile export makes this quick), then set the defaults in each app.
It doesn’t show on my phone
Phone apps often have their own, separate signature setting and may support plain text only. For example, the Gmail app has its own mobile signature, and if you don’t set one, Gmail uses the one from your computer. Check your app’s settings on the phone itself.
