Email Signatures

Overview

In short: open your email account's signature editor (Emails → Manage Accounts → Set signature), paste your signature into Signature (HTML), check the Preview and click Save. To include an image, host it online and reference its link in the HTML.

Add or edit an email signature

1
Open the signature editor
Go to Emails → Manage Accounts. In the account's row, under the Signature column, click Set signature — or View signature to edit an existing one. The Email Signature window opens.
2
Add or update your signature HTML
Paste (or edit) your signature in the Signature (HTML) field. Signatures are stored as HTML, so updating your signature later is just a matter of editing this HTML and saving again.
3
Check the preview
The Preview beneath the field shows how your signature will look in a sent email. Tweak the HTML until it looks right.
4
Save
Click Save — you'll see Email signature saved successfully. Reopen the account's View signature any time to make further edits.

Note: Signatures are set per account, so add one to each connected inbox you send from.

Add an image to your signature
1
Host the image and copy its link
Put the image somewhere with a public web link — your website, or an image host — and copy that link. In most places you can right-click the image and choose Copy image link (or Copy image address).
2
Add the image to your HTML
In the Signature (HTML) field, add the block below, replacing add_your_image_link_here with your image's link: 
<table cellpadding="0" cellspacing="0" border="0">
<tr>
<td>
<img src="add_your_image_link_here" alt="Email Signature" style="display: block; max-width: 600px; width: 100%; height: auto;">
</td>
</tr>
</table>
3
Preview and save
Check the Preview shows the image, then click Save.

Important: The image must be hosted somewhere we can load it from — a public web link (for example on your website or an image host). An image saved only on your computer, or behind a private or login-only link, won't display in the signature. Paste the image's public link into src.

Frequently asked questions

I don't have my signature as HTML — how do I create it?

Signatures are added as HTML. If you don't have it yet, you can turn a screenshot of how you'd like your signature to look into HTML with an AI tool (for example Claude or ChatGPT), or ask your IT team, then paste the result into the Signature (HTML) field. This is often handled by a company's IT team — and Keyhook support is happy to help.

Why is my image not showing?

Almost always because the image is not reachable from a public web link. Host it online and use that link in the image's src — a file saved on your computer, or a private or login-only link, won't load for your recipients.

Do I need to set a signature on every account?

Yes. Signatures are per account, so set one on each connected inbox you send from.
