SaaS Email Marketing Platform Testing

Hi! I’m looking for testers for a new SaaS project I’m developing.

It’s an automated email marketing platform where users can import their email contacts, create lists, prepare campaigns, upload their email content, preview it, check the mail quality score via Mail-Tester API, and finally send emails through multiple providers.

I would like you to sign up to the platform, explore all features, and give me detailed feedback.
Your feedback can be about:

Usability — What feels smooth, what feels confusing

Bugs or errors you detect

Suggestions to improve the overall UX

Ideas for new features

Any missing steps during list creation, campaign creation, or email sending

Any technical or UI issues you encounter

You can test things like:

Creating multiple contact lists

Adding emails manually, in bulk, or by uploading a .txt file

Creating campaigns and attaching multiple lists

Uploading email content for sending

Previewing the email before sending

Checking the Mail-Tester score

Overall workflow from registration to sending a test email

I’m looking for honest, detailed feedback that helps me improve the product before launch.
Thanks in advance — your insights will be extremely valuable!

By the way, what would be the cost for you to perform this testing and provide complete feedback?
