Lists

A list is a collection of contacts you can send to. Lists are the foundation of your audience — you import contacts into them, build segments on top of them, and target them with campaigns and automations.

What a list is for

Think of a list as a group of people who share a relationship with you — newsletter subscribers, customers, or event attendees. Most accounts need only a handful of well-organized lists. Within a list you can target specific groups using segments rather than creating a separate list for every audience slice.

Each list has its own overview — growth, engagement rates, and tabs for everything the list owns.

Creating and organizing lists

Create a list, give it a clear name, and you're ready to add contacts. Keep your structure simple:

  • Use a few broad lists (for example, “Newsletter” and “Customers”).
  • Differentiate audiences with segments and custom fields, not dozens of lists.
  • Reserve separate lists for genuinely separate audiences with different consent.

Consent and list health

Only add contacts who have agreed to hear from you. Clean, permission-based lists are the single biggest factor in deliverability. On paid plans, EmailFlow AI helps by running automatic verification on contacts as they're imported, flagging invalid and risky addresses before they can damage your sender reputation.

Finding lists with AI

The lists table has an Ask AI to filter box beside the search and sort controls: describe what you want — “newsletter lists sorted alphabetically” — and the AI fills in the table's normal search and sort for you, with a one-click Clear AI filters to undo. Each request uses one AI action from your AI credits. The campaigns table has the same box with status and date filters too.

Learning from unsubscribes

When a subscriber unsubscribes through the web flow, the confirmation page asks one optional question about why they left (too many emails, content not relevant, never signed up, or other — with an optional comment). The list overview shows a "Why people unsubscribed" card covering the last 90 days, with counts per reason and recent comments, so churn becomes feedback you can act on. If you customize the list's unsubscribe success page template, place the {{ REASON_FORM }} tag wherever you want the question to appear — leave it out and the page simply skips the question. The unsubscribe itself always completes first, and one-click unsubscribes from mail clients are never interrupted.

List limits

Your plan sets how many lists and contacts you can keep, and how many subscribers a single list may hold. If you approach a limit you'll see a clear prompt; higher tiers raise these allowances substantially. To learn how individual contacts work, continue to Subscribers & import.

Frequently asked questions

Should I make a new list for every audience? Usually not. A few broad lists plus segments and custom fields are easier to manage than many overlapping lists — and they avoid emailing the same person twice.

Can the same contact be on two lists? Yes. Reserve separate lists for genuinely separate audiences with different consent; otherwise lean on segments within one list.

What keeps a list healthy? Permission-based growth through forms, automatic verification on paid plans, and automatic suppression of unsubscribes and bounces — all handled for you.
