Pre-fill users names and emails in the form

I frequently use the native campaign feature in Senja where I upload a CSV of contacts and send out emails from Senja to collect testimonials. It would be great if:

1. You offered more fields for contacts so we can use first names, last names, company name, etc, in your native email tool

2. You allowed names and emails to be pre-filled in the form so that it is less friction for users to submit. Asking for contact information can feel invasive

3. We could customize the follow-up email language. Right now, you do follow-ups on days 1, 3, and 7. I have no visibility into what those emails looks like or say. Are they the same exact emails?

4. I want to be able to preview all emails before they go. You offer a preview for the initial email and the thank you email, but no inbox testing capabilities or previews for follow-up emails
