Frequently asked questions
Which email clients does it support?
Sigquill signatures are tested against Outlook (Windows & Mac), Apple Mail, Gmail, and Thunderbird. The nested-table HTML ensures consistent rendering even in Outlook 2016–2021.
Do you store my emails or inbox data?
No. Sigquill never asks for your email password or inbox access. You build your signature in the browser and copy it directly into your email client. We have no access to your emails.
What is the refund policy?
If you are not satisfied within 15 days of purchase, contact us and we will issue a full refund — no questions asked.
Is this a subscription?
No. Sigquill is a one-time purchase of $49 USD. You get lifetime access to the builder and all future updates.
Does the signature work on mobile?
Yes. Signatures are responsive by default — they adapt to narrower screens in mobile email clients while keeping the Outlook-safe table structure intact.
