Questions, answered
Will it actually work in Outlook?
Yes — that's the whole point. Outlook renders email with Microsoft Word's engine, which breaks most signature builders. SignStack outputs table-based, inline-styled HTML built specifically to survive it, so what you preview is what your recipients see.
Which email clients are supported?
Outlook (Windows desktop and web/New Outlook), Gmail, Apple Mail, and mobile mail apps. Each signature comes with copy-paste and one-click install instructions per client.
Can I manage signatures for my whole team?
Absolutely. Invite teammates by email, set brands they inherit, and manage roles. Update a brand's logo or colours once and it flows to everyone on that brand.
Do animated GIF banners work?
They animate in Gmail, Apple Mail and mobile. Desktop Outlook shows the first frame (a limitation of every signature tool), so we recommend designing banners whose first frame stands on its own.
What happens on the free plan?
You get one brand, up to three team members, and every template — free forever. Free signatures include a small “Powered by SignStack” line, which Pro removes.
Can I cancel anytime?
Yes. Pro is month-to-month with self-serve billing — upgrade, downgrade or cancel whenever you like.
