Sequences

Sequence structure

A sequence is a timed series of emails that subscribers progress through automatically. Each email in the sequence has its own delay — the time that passes after the previous email before this one is sent. This makes sequences ideal for onboarding flows, nurture campaigns, educational courses, or any communication that should unfold over days or weeks rather than arriving all at once.

Each sequence email is independent in terms of content and publishing state, but they share the sequence-level configuration for delivery connection, tracking settings, and sending schedule rules.

Connection and sending rules

Sequences are configured at two levels: sequence-level settings that apply to all emails in the series, and per-email settings that control each individual message.

Sequence-level settings:

• Email delivery connection: which provider sends all emails in this sequence. All emails in a sequence use the same connection.
• Reply-to address: an optional address where replies from subscribers should go if different from the From address.
• Track opens and clicks: enable or disable engagement tracking for the sequence's emails.
• Sending days: restrict email delivery to specific days of the week. Useful for ensuring emails arrive on business days only, or avoiding known low-engagement days.

Per-email settings include the delay before sending, the subject line, preview text, body content, and an optional audience filter to restrict which enrolled subscribers receive that specific email.

Drafts, publishing, and tests

Each email in a sequence has its own publishing state — draft or published. New emails start in draft and are not sent to enrolled subscribers until published. This lets you build out the full series over time, publishing each email when it is ready, without holding up the emails that are already complete.

Before publishing an email, use the Send test option in the email's settings drawer to deliver the message to a real inbox. This confirms subject line rendering, image loading, and content formatting before the email reaches real subscribers.

You can also edit a published email to update its content. The updated version applies to subscribers who have not yet received that email — subscribers who have already passed that step in the sequence see the original version.

Analytics and enrollment

The sequence analytics view shows performance at both the sequence level and the individual email level:

• Sequence level: total enrolled subscribers, active (still progressing), completed, and removed.
• Email level: sent count, opens, clicks, unsubscribes, bounces, and complaints for each email in the series.

Use email-level analytics to identify where subscribers lose interest — a sharp drop in opens at email three, for example, suggests the content or timing for that step needs attention.

Subscribers can be enrolled in a sequence in several ways:

• Added manually from the Subscribers page (individually or in bulk).
• Included in a CSV import with a sequence assignment.
• Enrolled automatically by an automation action step.
• Enrolled when they click a magic link with sequence enrollment configured.
