Everyone has written an email with ChatGPT by now: you copy the text, paste it into your email marketing tool, pick the list, check everything and send. The AI did the writing, but you did everything else.
Now that assistants can connect to applications through the Model Context Protocol (MCP), there is another way to work: the assistant works directly in your account. It reads your lists and statistics, prepares the campaign, and all you have to do is say yes. Here is what that actually changes, and what it doesn't.
Before and after: the same week, two ways of working
| What you want to do | Without a connection | With a connected assistant |
|---|---|---|
| Find out which newsletter performed best | Open three reports, note the rates, compare | “Compare my last three newsletters and tell me which subject line worked best.” |
| Follow up with people who didn't open | Export the non-openers, create a list, duplicate the campaign, rewrite the subject line | “Prepare a follow-up to the spring offer for everyone who didn't open it.” The campaign waits for your approval. |
| Remind workshop attendees | Find the list, write a 160-character SMS, schedule it | “Send a reminder SMS to everyone registered for Thursday's workshop.” |
| Clean up before a big send | Hunt down dormant lists, unsubscribes and bounces | “Which lists haven't received anything in six months?” |
| Check your balance | Log in, go to your account | “How many SMS credits do I have left?” |
There is no magic: the assistant uses the same functions you use in the application. The Mailpro MCP server gives it 51 of them: reading contacts, lists, templates, campaigns and their statistics, creating contacts and templates, preparing campaigns, sending an email or an SMS.
What really changes
1. You ask instead of searching
The first gain isn't writing, it's reading. Your campaign figures already exist, but nobody has time to cross-check them. A connected assistant does it in one question: which subject line works, which day, which list is dropping off. It answers with your real figures, not with averages found online.
2. The campaign arrives ready, not just the text
The assistant writes in your tone (give it a past email), creates the template in Mailpro, picks the list and prepares the campaign. Your job becomes a review: you approve, you edit, or you refuse.
3. Small sends stop piling up
A reminder SMS, a follow-up to ten people, an email to one customer: the two-minute tasks you put off all week are handled in one sentence.
What doesn't change (and that's good news)
- Your deliverability: emails go out from your domain, through Mailpro's infrastructure, with SPF, DKIM and DMARC. An assistant sending from a personal mailbox would quickly end up in spam.
- Your unsubscribes and bounces: they stay excluded, whoever is sending.
- Your credits: a send made by an assistant costs the same as a send from the application (the details).
- Your data: your lists and statistics stay hosted in Switzerland. However, whatever the assistant reads to answer you goes through the AI you chose: worth knowing before you start.
The limits to know
AI can make mistakes. Wrong list, wrong date, wrong tone: that's why every send waits for your approval by default. Once you trust it, you can let an assistant send directly, within a daily cap you set, with a log of everything it did and a button to suspend it all.
Not all plans are equal. Claude accepts a custom connector even on the free plan; with ChatGPT, custom MCP apps depend on your plan (which plan you need).
It isn't an autopilot. The assistant doesn't decide on a strategy by itself: it carries out what you ask, quickly and well. The more precise your request (list, tone, date), the better the result.
Our advice: start with questions (statistics, lists, credits). There is no risk, and you'll quickly see how well the assistant understands your account.
Where to start: 10 minutes
- In your Mailpro account, on the AI Assistants (MCP) page, copy the server address.
- Add Mailpro to your assistant: Claude, ChatGPT, Mistral (Vibe), Gemini or Copilot.
- Sign in to Mailpro and accept the requested permissions (OAuth sign-in, no key to copy).
- Ask a first question about your statistics, then ask for a campaign: it will wait for your approval.
