How to add an email signature in Spark
Setting up a professional email signature in Spark takes just a few minutes with Signaturely. Build your signature with our free generator — add your logo, social icons, contact details, and brand colors — then copy the ready-made HTML and paste it into Spark’s signature settings. The result renders correctly in MacOS and stays consistent across every message your team sends.
Because Spark handles HTML signatures natively, you don’t need any plugins or technical setup. Everything is embedded in a single block of table-based HTML that survives forwarding, replies, and dark-mode rendering.
Step 1 — Generate
Use the Signaturely generator to design your signature: name, role, logo, social icons, and banner. Live-preview as you type.
Step 2 — Copy HTML
Export or copy the generated HTML with one click. The markup is table-based and email-client safe, ready for Spark.
Step 3 — Paste & send
Paste it into Spark’s signature settings, save, and send yourself a test email to confirm spacing and images.

Will my Spark signature work on mobile and desktop?
Signatures generated with Signaturely are responsive table-based HTML, so they render correctly in MacOS and adapt to the width of the reading pane on both desktop and mobile.
Can I include my company logo and social icons in Spark?
Absolutely. The generator supports logo uploads, social media icons, banners, custom colors, and fonts — everything is embedded in the HTML you paste into Spark.

Most users finish in under 5 minutes: generate the signature, copy the HTML, paste it into Spark's signature settings, and send yourself a test message to confirm the formatting.
