In Persistiq, you can either add your signature in the template, or set a global signature through the mailbox settings that are automatically attached to outgoing emails. 

Note that your Gmail, Outlook, and other email clients' signatures are not automatically attached to your Persistiq emails. However, if the signatures are set up by your IT department, your signature might be attached automatically. To confirm that, create a test campaign, add any email address that you have access to, then send a test email. Check the inbox of that email address you used and see if the signature is auto-attached. 

To set up a global signature in the Mailbox settings, follow the steps below: 

Step 1: Access Setting and Billing from the lower left menu and click on Mailbox;

Step 2: Scroll down to "Signature", enter your information:

IMPORTANT: Do not add your name to the email template itself if you are using a global signature or disable the global signature if you prefer to add signatures in your email templates. 

If you're copy-pasting the signature, send a test email and open the test email on incognito to see if the format or the image appears correctly.
