To make it easier to manage e-mail lists across captures, you can create an e-mail App. This App contains the list of e-mail addresses and the template to use. You can then use this App in multiple captures.
The verification feature will check that none of the e-mail addresses are blocked by Blitapp. See this blog post to understand why an e-mail may be blocked.
Note that you can combine the e-mail App and the e-mail feature of the capture; we can send e-mail to both the e-mail list and addresses contained directly in the capture.
