Behavly finds who to follow up.

The snippet sees what each person does on your site, and Behavly spots the groups in it: people who visited pricing then went quiet, hit friction on a page, or never got going. Or describe a group in a sentence and see who matches first. A Pattern Campaign then follows them up, once or always on.

Start for freeHow patterns work

One API call starts the follow-up.

Your backend sends Behavly an event when something happens to a person, like a declined card or an ending trial. Every Trigger Campaign that starts on it takes them in the moment it arrives, and the event's details can fill the emails.

Questions, answered.

Seven things people ask before they sign up. For everything else, the Help Center has 52 articles on how each part of Behavly actually behaves.

01

What is Behavly?

Behavly is behavior-based email for SaaS and other products people sign in to. A snippet records what each signed-in user does on your site. You describe a follow-up in plain words, Behavly lays out the path of emails, waits and branches, and Behavly Agent writes each email from that person’s own activity, sent from your own mailbox or email service. Replies come back to a shared Inbox with each sender’s activity on your site alongside. It is not a cold-outreach tool: everyone in your workspace signed in on your site, filled in one of your forms, or was imported by you.
02

How do I get started?

Three steps. Add the tracking snippet to your site, which is where all behavior data comes from. Connect a mailbox, which sends your campaigns and feeds the Inbox. Then create your first campaign: pick a group or a trigger, and describe the path in words or build it step by step. Nothing sends until you activate it.
03

How does Behavly know who a visitor is?

The snippet detects a signed-in session on your site by itself. There is no identify call to add. Each identified user is listed once, as a person: visits from a laptop and a phone are merged under the same email. Visitors who are not signed in appear separately as anonymous sessions.
04

What is Behavly Agent?

The AI built into Behavly. Ask in your own words and it does the work in your workspace: it builds a campaign, finds a pattern, drafts a reply or reports how a campaign is doing. In a campaign it writes each email for one person from what they did. Nothing changes until you confirm, and nothing sends until you activate it.
05

Do I review emails before they send?

Yes. Turn on Review in a campaign and every email Behavly writes waits for you, then sends when you release it. Before you activate, Preview writes any email for a real person without sending it. In the Inbox, Behavly writes the draft and you send it.
06

Which email accounts can I connect?

Any mailbox that supports IMAP and SMTP: Gmail or iCloud with an app password, Titan, Zoho, Fastmail, your own domain’s mail host. Or an email service, connected with its API key: Resend, Amazon SES, Postmark, SendGrid, Mailgun, Brevo, Mailchimp Transactional or MailerSend, plus that address’s inbox over IMAP so replies come back. You can connect several, and replies to a connected mailbox land in the Behavly Inbox with each sender’s activity on your site alongside.
07

How is my customers’ data handled, and can I limit what reaches AI?

You stay in control. AI can be turned off for your whole workspace, and when it is on you decide how customer data is treated before it is used and how long behavior data is kept. Visitor IP addresses are never stored. Every account, campaign and workspace action is recorded in an audit log you can export.
