Signature Foundry is a plugin on your own WordPress install. Signature data never leaves infrastructure you control.
We count impressions and clicks per banner and per sender. We never record who received the email.
Start with one person. Most enterprise signature vendors will not sell you fewer than ten seats.
Yes. Build your brand kit here first, then switch the deployment over. Both signatures can coexist during the changeover because neither one touches the other.
No. You can run Signature Foundry for one person or eight thousand. Most competitors set a floor of ten to twenty-five seats.
It stays with Exclaimer — we cannot import another vendor’s analytics. New campaigns start counting here from day one.
Everything is unlocked during the trial, including campaigns and analytics.
