List preparation decides whether a campaign is viable at all.Sun, 27 Sep 2026 00:00:00 GMTListsDeliverabilityhttps://sendlyapp.com/blog/unsubscribe-handling-that-protects-your-domain/https://sendlyapp.com/blog/unsubscribe-handling-that-protects-your-domain/An unsubscribe link that renders correctly and does nothing is worse than none at all, because the recipient who tried to leave reaches for the spam button instead. The failure is common and invisible from the outside.Sun, 27 Sep 2026 00:00:00 GMTDeliverabilityCompliancehttps://sendlyapp.com/blog/the-email-setup-that-decides-whether-you-reach-the-inbox/https://sendlyapp.com/blog/the-email-setup-that-decides-whether-you-reach-the-inbox/Most deliverability problems are decided during setup, not during writing.

The features that decide whether you keep a sending domain are unglamorous, and several of the headline ones are actively harmful.Sun, 27 Sep 2026 00:00:00 GMTDeliverabilityInfrastructurehttps://sendlyapp.com/blog/what-can-spam-actually-requires/https://sendlyapp.com/blog/what-can-spam-actually-requires/Commercial email to a business address is legal in the US without prior consent, which surprises people on both sides of the argument. The requirements are short, specific and mostly about honesty, and the one people miss is the postal address.Sun, 27 Sep 2026 00:00:00 GMTCompliancehttps://sendlyapp.com/blog/when-to-pause-a-campaign-and-what-to-check-first/https://sendlyapp.com/blog/when-to-pause-a-campaign-and-what-to-check-first/Two numbers should stop a campaign immediately, and the instinct in both cases is to push through and fix it next time. That instinct is the expensive one, because the damage attaches to the sending domain.Sun, 27 Sep 2026 00:00:00 GMTDeliverabilityMetrics
