Can I open-source Sendcore?
NOT REALLY · nothing credible yetNo credible open-source replacement for Sendcore yet — Listmonk and Keila are the closest escape hatches, but they don't cross the moat. Merchants pay for the parts nobody enjoys building: staying installed and billed inside Shopify, keeping consent and suppression records defensible when a customer or a regulator asks, and getting mail into inboxes from a domain the merchant owns. The campaign editor is the part that demos well and the part an agent reproduces in an afternoon, right up to the moment other people's content meets other people's inboxes. Pasted rich text with mixed inline formatting, merge tags that must not eat the punctuation around them, product blocks that survive Outlook, automation timing that has to line up with a real order: none of these are design problems. They are a backlog you only discover by sending mail on behalf of other businesses, and grinding through it is what separates a demo from something a shop trusts with its list.

What do I lose by replacing Sendcore?
Honestly: App Store distribution: OAuth install, app review and the mandatory GDPR data webhooks; billing that appears on the merchant's own Shopify invoice instead of a separate card; domain authentication onboarding and per-tenant sender reputation; bounce, complaint and suppression handling; order-level revenue attribution and automations that fire on real store events.
