Master list hygiene, boost email deliverability, and optimize your outreach campaigns with actionable guides.
Black Friday is the best week of the year for email revenue. It’s also the worst week of the year to get careless about who you’re sending to. Both are true at once, and most Black Friday email marketing advice only prepares you for the first one. The volume numbers alone explain why this week … Read more
Search “does Gmail have a feedback loop” and you will find dozens of guides confidently answering no. That is not quite right. Gmail runs a feedback loop, just not the kind Yahoo or Microsoft run. This is not a small detail. It is the reason so many setup guides send you looking for a Gmail … Read more
Building an email list gets treated as a single problem with one answer. Get more addresses, as many as you can, as fast as you can. That’s only half the problem. The other half shows up months later. The pop-ups have converted, the contest has ended, and the list looks bigger than it did last … Read more
Search “one-click unsubscribe” and you’ll get a straight yes on whether it’s required. That yes is only half true, and which half depends on which requirement you’re actually asking about. There are two separate rules stacked on top of each other here, and most guides treat them as one. The first has applied to you … Read more
Search “email compliance” and you land in one of two different conversations. Half the results are about encrypting internal messages and meeting SEC retention rules, a compliance officer’s problem.

Google’s own FAQ is direct about it: bulk sender status “doesn’t have an expiration date.” Cutting your sending volume back down afterward “will not affect” that classification. Most content covering Google & Yahoo bulk sender requirements skips this detail entirely, … Read more
AI in email marketing gets talked about as if it’s one capability. In practice, it splits into two fundamentally different technologies, and each one solves a different problem. Predictive AI looks at a subscriber’s existing history: purchases, opens, clicks, browsing behavior. It turns that history into a decision, like when to send, who to send … Read more
A subscriber joins your list at two in the morning, and a welcome email is already in their inbox nine minutes later. That’s long before you’ve even opened your laptop the next day. A shopper abandons a cart over lunch, and a reminder is waiting by the time they’re back at their desk. That’s email … Read more
Automated flows make up about 2% of the emails an ecommerce store sends. Omnisend’s own 2026 data puts their share of total email revenue at 37%.
