Those are different numbers for a real reason, and most tools blur them into one “integrations” count. Here is which is which, and exactly what data crosses.
Every provider you connect receives the lead. One popup, all of them.
No tags, no custom properties, no quiz answers, no behavioural profile. The record your provider receives is a contact type and a contact value. Segmentation, tagging and enrichment happen in your email platform, which is where the rest of your marketing data already lives and where those tools are better than ours would be.
Reading a cookie is cheaper than writing an adapter, so this list is longer.
An audience rule can check whether one of these providers has already set a marketing cookie for this visitor and withhold the popup on that basis. That is how someone who joined your SMS list stops being shown your email signup. SMSBump and Yotpo appear here but not above — we can recognise them, we cannot sync to them.
Including what happens if your provider is not on the list.
Six, directly: Klaviyo, Omnisend, Mailchimp, Attentive, Postscript, Drip. A confirmed signup is pushed to every provider you have connected, so if you run email in one tool and SMS in another, one popup feeds both without you exporting anything.
Only the email address or phone number, and nothing else. There is no tag, no custom property, no quiz answer and no behavioural profile — the payload is the contact type and the contact value. We would rather state that plainly than let a feature list imply we enrich the record, because we do not.
Two different operations. Syncing a signup requires an API adapter written against that provider, and we have six. Detecting whether a visitor already subscribed only requires reading a marketing cookie that provider already set, which is cheaper — so that list is seven and includes SMSBump and Yotpo, which we can recognise but cannot write to. It means a visitor who joined your list through one of those can still be excluded from the popup.
Then we cannot sync to it today, and the honest answer is that you should weigh that heavily rather than assume a workaround. Signups are still captured and visible in the dashboard, so nothing is lost, but the automatic hand-off that makes this useful will not be there. If you run something outside the six, tell us — the adapter list is short enough that demand genuinely decides what gets added next.
Yes, and the ordering matters. With double opt-in selected, the address stays provisional until the confirmation link is clicked, and only a confirmed subscriber is pushed to your provider. Unconfirmed addresses never reach it, so they never count against its contact limits or drag on your engagement metrics. Both 2 modes are per-campaign rather than account-wide.
Yes — there is a Shopify app, and cart conditions read store state so a popup can fire on cart value or on an item being added. That is separate from the email provider question: Shopify is where the popup runs, and the six providers are where the subscriber ends up.
