The Claude connector can now make changes

The FirstSales connector for Claude used to only read your data. It can now make changes too, and Claude asks you to confirm before each one.

What changed

The connector can now:

• update a campaign's steps, lists and sending mailboxes;
• add Blocked Domains and check whether an address is blocked;
• add contacts to lists or remove them;
• check your email authentication setup;
• connect a Cal.com booking link;
• draft, schedule and send direct emails.

Every change asks for your confirmation in Claude first. The connector offers only the tools we have tested end to end.

How to use it

Connect FirstSales in Claude, then ask in plain words, such as "add example.com to my blocked domains" or "move these contacts to my Q4 list". Claude shows you the change and waits for your yes.

Why it matters

You can now run day-to-day FirstSales work from a chat, without switching tabs, while still staying in control of every change.
