Grow an email list of people who asked to hear from you

A landing page offers your free resource with double opt-in, and each subscriber gets a tag for the resource chosen; a welcome sequence then sends the delivery email automatically. Where it stops: Automatic delivery by sequence needs Creator; the SparkLoop referral system needs Pro.

Embedded forms, pop-ups and landing-page forms add people to a group, and that group starts an automation that delivers the guide; double opt-in is available on forms. Where it stops: Over the Free subscriber limit, forms keep collecting with no error shown, but new subscribers receive nothing.

Subscribe forms, sign-up flows, a link-in-bio page and a website collect readers on every plan, while the recommendation network trades sign-ups with other newsletters and a digital product can serve as the lead magnet. Where it stops: Free allows one digital product; the referral program is not on Free.

Sign-up forms in the base email plan, tuned by AI form optimization; on Shopify, the guided setup creates a sign-up form, a welcome email and an abandoned-checkout flow. Where it stops: Every collected address counts as billable until suppressed, and the Free plan caps profiles.

Sign-up forms on every plan collect addresses, the WordPress plugin connects forms on a WordPress site, and Zapier or the API can add contacts from other tools. Where it stops: Landing pages start on Standard and pop-ups on Professional; the welcome automation is limited on Free and Starter.

A web sign-up form on every plan, placed where people already are (website footer, booking confirmation, event page), feeds a welcome automation; a landing page can do the job without a website. Where it stops: No free plan.

Forms capture contacts on every tier and feed its automations; from Plus, modal forms, landing pages, site messages and Facebook lead ads add more capture points. Where it stops: No free plan; Starter has no landing pages or site messages.
