Create your signatureRe: What it is
An email signature banner is a clickable image or CTA block appended below your signature. It turns every email into a marketing channel — perfect for promoting events, product launches, blog posts, or seasonal campaigns. With your team sending hundreds of emails daily, a signature banner delivers massive reach at zero cost.
Re: How it works
Step 1
Create a banner image at the recommended size of 480x60px (or up to 480x120px for larger promotions). Keep the file under 200KB. Use PNG or JPEG format and host it on a public HTTPS URL.
Step 2
Enter your hosted banner image URL and the destination link (where the banner should point to) in BrandFooter's generator. Add UTM parameters to your link for click tracking.
Step 3
For better Outlook compatibility, choose BrandFooter's text-based CTA banner option. Add a headline, short description, and a button — no image required, and it renders perfectly in every email client.
Step 4
Click 'Copy HTML' to copy your complete signature with the banner. Paste it into your email client's settings. Update the banner whenever you have a new campaign.

Re: Common questions
Common questions about a banner in email signatures.
The recommended size is 480x60px for a standard banner or 480x120px for a larger promotional banner. Keep the file size under 200KB for fast loading. Always stay within 600px maximum width to ensure compatibility across email clients.
It depends on your audience. Image banners are more visually striking and better for brand-heavy promotions. Text-based CTA banners are more reliable across email clients (especially Outlook), load faster, and have lower spam filter risk. For maximum reach, text CTAs are the safer choice.
Image banners display in Outlook but may be blocked by default as Outlook blocks external images for security. Recipients must click 'Download pictures' to see them. Text-based CTA banners avoid this issue entirely and render perfectly in all versions of Outlook.
Update your banner every 2-4 weeks, or whenever you launch a new campaign, event, or promotion. Stale banners lose effectiveness quickly. With BrandFooter's team features, you can update banners across your entire organization in one action.
Yes. Add UTM parameters to your banner destination URL (e.g., ?utm_source=email&utm_medium=signature&utm_campaign=spring-promo). This lets you track clicks, conversions, and ROI in Google Analytics or any analytics platform.
Banners alone won't trigger spam filters if done correctly. Keep image file sizes small (under 200KB), use HTTPS URLs for image hosting, avoid excessive links in your signature, and don't use spammy language in your CTA. Text-based banners carry the lowest spam filter risk.
