Questions other Mails.so users had before signing up
Do I need to know how to code?
Not even a little. If you can use Mails.so today, you can set this up. You'll connect Mails.so, tell your AI what it should help with, and you're live. The whole thing is built for coaches, course creators, agencies, and operators — not engineers.
Will my clients know they're talking to an AI?
Only if you want them to. Your FormWise AI is trained on your voice, your offer, and the way you actually communicate — so it sounds like a thoughtful team member, not a clunky chatbot. Most people can't tell.
Can I make it sound like me?
Yes. You can give your AI examples of how you write, the questions you usually ask new clients, the way you handle objections, and the language you use about your offer. The more you give it, the more it sounds like you wrote it.
What if I want to take over a conversation?
You're always in control. You can step in at any point, take over from your AI, or stop it from sending messages until you've reviewed them. Think of it as a teammate, not a replacement.
Is my client data safe?
Yes. Your Mails.so login and client information stay scoped to your workspace. We don't sell it, we don't share it, and we don't use your data to train anyone else's AI. You can disconnect Mails.so or delete everything any time.
What happens when Mails.so updates their app?
We handle it. When Mails.so adds new features or changes how something works, we update the integration in the background. You don't have to do anything — your AI just keeps working.
How fast can I actually get this running?
Most people are up and running the same day they sign up. Connecting Mails.so takes a few minutes. Teaching your AI to handle the work the way you'd want it done is the part worth slowing down for.
What is FormWise?
FormWise is the AI agent builder for coaches, course creators, and agencies. You connect the apps you already use — like Mails.so — train your AI on your offer and voice, and let it handle the work you've been doing manually: onboarding, follow-ups, support, admin. No code, no developers, no engineering team required.
Can I sell AI agents to my clients?
Yes. A lot of FormWise users build AI assistants and sell them as part of their offer — done-for-you AI setups, white-label assistants for client businesses, custom GPTs trained on a client's brand. You can charge a setup fee, a monthly retainer, or both.
Can I embed my AI on my website or in my course?
Yes. Every AI you build in FormWise can be embedded on your site, dropped into your course platform, or shared as a standalone link. Your clients and students just open it like any other web page — no app to download, no login hoops.
Do I need to know anything about AI to use this?
No. If you can describe what you want your AI to do in plain English — "greet new clients, ask these 3 questions, book them a call" — FormWise can build it. We handle the models, the prompts, the connections. You handle the part you already know: what your business actually needs.
