Mailbox providers such as Gmail and Microsoft Outlook now expect bulk senders to publish SPF, DKIM and DMARC records, to offer a clear one-click unsubscribe and to keep spam complaints low. Stores that skip this work see promotional messages land in the spam folder even when the content is fine. We confirm the records, set up a dedicated sending domain where it helps and ramp volume gradually on a new domain before any large campaign.
Growing the list without filling it with dead addresses
A popup that trades a discount for any address tends to attract people who unsubscribe after one use. We look at where signups come from, test quiz or early access offers suited to your products, add confirmation where bounce rates suggest typos or bots, and sunset subscribers who have not opened or clicked in a long stretch. A smaller engaged list usually earns better inbox placement than a large stale one.
On the technical side, your email platform needs clean events from the store: viewed product, added to cart, started checkout, placed order, fulfilled order. Missing or duplicated events break flows silently, so we audit that integration before rewriting a single message.
