Verify your email
The one step between signing up and using the product.
Open the email from GetSimpleSign. The subject line says to confirm your email address.
Press the link in it. That is the whole step — you do not need to type anything.
If the page says the link has expired, go back to the sign-up screen and press Resend verification email. Links expire on purpose: an old one sitting in a mailbox is a way in.
You should see
You are signed in, and looking at your empty template library.
If it did not work
Nothing arrived. Look in spam or junk, and check the address you typed for a slip. If your organization filters mail, ask whoever runs it to allow mail from GetSimpleSign.com.
You pressed the link on a different device from the one you signed up on. That is fine — it works anywhere.
