Send outreach from your own mailbox, through your AI agent.
First100 connects the mailbox you already use, such as Google Workspace, Microsoft 365 or any SMTP provider, and lets your AI agent send outreach emails from it through MCP. The agent writes each message and is told to show you the recipients before sending; First100 sends them one at a time with a 1.5 second pause and an opt-out line.
How do I connect a mailbox?
Open Accounts in the First100 dashboard and fill in the outreach email card, or ask your agent to run set_smtp_config. Google and Microsoft mailboxes need an app password. First100 logs in to the server before saving, so a wrong password or host is reported at once and nothing is stored.
How is the password stored?
Encrypted with AES-256-GCM. The dashboard and the tools only ever show whether a mailbox is connected, never the password. Only public mail servers on ports 465, 587, 2525 or 25 are accepted.
How many emails can I send?
Outreach emails per month: 50 on the week trial, 500 on Starter and 1000 on Pro. Set up SPF, DKIM and DMARC for the sending domain first, or the messages are likely to land in spam.
What does each email contain?
The subject and body your agent wrote, with any HTML in it escaped, and an opt-out line added at the end. It goes out from your address, so replies land in your own inbox and the conversation continues there, not in First100.
Where do the recipients come from?
From you, or from find_businesses, which searches local businesses through Google Places. First100 does not sell or enrich contact lists.
