Send from your Microsoft 365 mailbox
Enable SMTP AUTH on the mailbox and connect it to Infiara over smtp.office365.com, port 587 with TLS. Infiara sends a test before any campaign uses it, then sends every message as that mailbox.
Microsoft 365 automation
Email automation for Outlook and Microsoft 365.
Send personalized outreach from the Microsoft 365 mailbox your company already pays for. Infiara handles sequences, follow-ups, reply detection, and tasks.
In short
To automate email from Outlook or Microsoft 365, enable SMTP AUTH on the mailbox, connect it to Infiara over smtp.office365.com on port 587, import contacts, and launch a sequence. Infiara sends as your mailbox, stays under the daily cap you set, and stops following up when someone replies.
Campaigns that respect Microsoft limits
Set a daily cap on each mailbox that sits under your Microsoft plan’s limit. Campaigns rotate across all attached mailboxes and only send in the weekday window you choose.
Automatic follow-ups for Outlook
Outlook has no built-in sequence that stops when someone replies. Infiara does: bump and close on your cadence, and stop the instant a contact answers.
AI reply sorting
Replies to your Microsoft 365 mailbox are read over IMAP and labeled Meeting, Interested, Pricing, Out of office, or Not interested. Positive replies open a task for a person.
