Frequently Asked Questions
When should I use a plain text signature instead of HTML?
Plain text signatures are ideal when emailing security-conscious recipients, when maximum compatibility is needed, or when your organization prefers a minimalist approach.
Can plain text signatures include links?
You can include full URLs (e.g., https://example.com), but they won't be styled as clickable hyperlinks. Most email clients will auto-detect and make them clickable.
Are plain text signatures better for deliverability?
They have a slight edge because there is no HTML to trigger spam filters. However, well-coded HTML signatures rarely cause deliverability issues.
How do I manage plain text signatures for a team?
Signature management platforms like Siggly can deploy both HTML and plain text versions of signatures to ensure every format is covered.
