Can Hubi send from any address, or only verified senders?

Postmark requires a verified sender signature or domain, so Hubi can only send from addresses your account has already verified. It cannot send from an unverified address on its own.

Is Postmark right for marketing blasts, or just transactional mail?

Postmark is built for transactional email like receipts, resets, and notifications, and that is what Hubi sends through it. Bulk marketing campaigns belong on a tool designed for that, which you can connect separately.

Will Hubi send a customer-facing email without my review?

By default Hubi drafts the message and shows you the recipient and content for approval before it sends, since these reach real customers. You can set standing rules for routine sends you want to go out automatically.

Can Hubi trigger a Postmark email from another tool?

Yes. You can chain Postmark with anything else you've connected - for example, when a new order lands in your store, Hubi can send the confirmation email through Postmark in one instruction.

Communication Transactional Email

A receipt or password reset that lands in spam costs you a customer, and chasing why a single email bounced means digging through logs. Hubi sends transactional email through Postmark, pulls delivery and bounce details for a specific message, and manages templates, so you can send and troubleshoot from a plain request.
