Write the welcome, follow-up and reminder emails once and let a trigger send each one when a subscriber signs up, clicks or buys.

For anyone asking: How do I send the right email automatically when someone signs up or buys?

Tools that do it

Each one's way of doing it, and the point where it stops.

Klaviyo Does it

Flows run on store events from your commerce integration, and pre-built abandoned checkout, welcome, post-purchase and win-back flows are ready to switch on and adjust. Where it stops: On Free, flows only go live under the free profile cap; a badly built flow keeps running without warning.

Kit Does it

A form or tag starts a welcome sequence, and a purchase tag starts a post-purchase automation for onboarding, care guides, review requests or a cross-sell. Where it stops: No abandoned-cart trigger. Automations stop running if the account drops to Free.

MailerLite Does it

A welcome series starts whenever someone joins a group; paid plans add abandoned-cart, purchase and win-back flows through store integrations, and auto-resend reaches non-openers. Where it stops: Free allows automations with tight caps. Stores that rely on Shopify flows should test first.

Brevo Does it

Standard runs abandoned-cart reminders, post-purchase follow-ups and win-back flows for any number of contacts, and web and event tracking triggers messages from site behavior. Where it stops: Free and Starter cap how many contacts enter automations; the Free daily send cap can delay triggered emails on busy days. Confirm the Shopify integration in writing.

ActiveCampaign Does it

A multi-step automation builder runs abandoned cart on every tier; browse abandonment fires when someone views a product, and split automations and predictive sending branch and time the series. Where it stops: No free plan. Starter has a small cap on actions per automation, and a condition or a wait each counts as one.

Automations are built from templates: a welcome email on every plan, automatic resend to non-openers, and abandoned-cart reminders on the top plan. Where it stops: Template-based rather than a free-form flow builder, with a thin customer record; Lite cannot resend to non-openers.

Mailchimp Partly

Automation flows send on triggers, from welcome automations to abandoned-cart flows that run once your store is connected. Where it stops: The Free plan does not carry the abandoned-cart automation; trigger-based sends make monthly volume harder to predict.
