Alyssa Dulin is Kit's deliverability expert.
She joined us to pull back the curtain on one of the most misunderstood forces shaping newsletter success: deliverability.
We sat down with her to unpack why emails land in spam, what the big Gmail and Yahoo changes really mean for individual creators, and how to build a sending reputation that lasts. From domain warmups to fake opens to bot clicks, this episode covers the stuff most newsletter creators won't learn until something goes wrong.
