The next email waits for what each person does.

Hold the next email until someone opens, clicks, visits a page or uses your product. Each email is written for that one person.

Let Behavly build the campaign, or build it yourself.

Say who it is for and what to send, and Behavly sets up the emails and the days between them. Or add each step yourself.

When something happens in your product, the follow-up starts.

Your product sends Behavly an event, like a failed payment, and a Trigger Campaign takes that person in the moment it arrives.

See where each person clicked, got stuck and stopped scrolling.

Add the snippet once. Clicks, rage clicks, movement and scroll are painted on your real site, for everyone or one person.

Each reply arrives with the sender’s history.

Every reply arrives with the sender’s site activity beside it. Answer it yourself, or let Behavly draft one for you to edit.

Emails thatlook likeyour brand.

Behavly designs whole emails and templates from your brand: your logo, your colors, your images. Every block stays editable.

One product. Not four tools that don’t talk to each other.

Tracking, email, the reply inbox and insights all read the same behavior data.

Everything a follow-up needs, already built.

Patterns, testing, review, brand design, languages and results, ready when you need them. You add the snippet and choose what to send.

  • Patterns

    Patterns Behavly finds for you

    Behavly spots the groups in your own users: visited pricing then went quiet, hit friction on a page, never got going. Or describe one in a sentence and see who matches before anything sends.

  • Always on

    A path that keeps running for everyone who joins

    Set a campaign to Always on and everyone who joins the group later starts the path too. It runs until you pause or stop it.

  • A/B test

    Test two versions of any email

    Try a second version of a step on half the people who reach it. Each person always gets the same one, and Behavly names a winner once the results are clear.

  • Test send

    Send the whole path to yourself first

    Every email on the path, written for one real person, arrives in your own inbox marked [Test]. Waits are skipped, and only you receive anything.

  • Control

    Read every email Behavly writes before it goes out

    Turn on Review and each email Behavly writes waits for you, then sends when you release it. Nothing goes out until you activate the campaign.

  • Design

    Emails designed from your brand

    Behavly designs whole emails and templates from your brand: your logo, your colors, your images. Every block stays editable.

  • Languages

    Every email in the reader’s language

    Behavly can detect each person’s language and write their email in it, or you set the language of an email yourself. It writes in 23.

  • Leads

    Form leads, followed up on their own

    People who leave their email in a form on your site are kept apart from signed-in users, as Form leads, so a campaign can give them a path of their own.

  • Insights

    See who came back, and how fast

    Follow how people re-engage after your emails and how long it takes, and see which campaigns did best.

Three steps to your first follow-up.

Paste one snippet. The app walks you through the rest.

Step 1

Add the snippet

One tag on your site. Signed-in users are recognized automatically, with no extra code.

Each person is listed once, across laptop and phone.

Step 2

Connect a mailbox

Any IMAP/SMTP mailbox: Gmail with an app password, Titan, Zoho, your own domain. Every email goes out from your own address.

Replies to your campaigns land in the Behavly Inbox.

Step 3

Build a campaign

Pick a group or a trigger, then describe the path in words or build it step by step. Nothing sends until you activate it.

Turn on Review to read each email Behavly writes before it goes out.

Questions, answered.

Seven things people ask before they sign up. For everything else, the Help Center has 50 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. In its chat you 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, describe a follow-up in words and Behavly lays out the path: emails, waits, and branches on what each person did, like opening the last email or logging in. Behavly Agent then writes each email for one person from their activity. The path runs as a campaign. A Pattern Campaign starts from a group, such as all users or a behavior pattern, and runs once or stays always on for everyone who joins. A Trigger Campaign starts the moment your product sends an event, like a failed payment. By default a person leaves the path when they reply. Every campaign type works on every plan, Free included.
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. 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.
