Common Email Client Quirks (And How We Solve Them)

Email signatures frequently collapse in Gmail, Outlook, or Apple Mail. Here is how our compiled HTML prevents formatting disasters.

Target: iOS Mail Stripping Inline Styles

Issue:Pasting formatted HTML directly into iPhone Mail settings strips font families and colors.

Solution:After pasting into iPhone Settings > Mail > Signature, simply shake your iPhone and tap 'Undo Change Attributes' to preserve the original rich HTML.
Target: macOS Mail Image Duplication

Issue:Signatures duplicated across multiple accounts in Apple Mail can lose image links.

Solution:Our CDN assets use immutable caching headers to ensure images persist across all connected iCloud accounts.
