Sending teaser emails before a product release can be a smart move if it is done the right way. These emails help create early interest by giving small hints about what's coming without revealing everything. For example, you can share a short message, a blurred image, or a countdown to the release day. This keeps people curious and reminds them to check back later. However, sending too many teasers might make people lose interest if the wait feels too long. It's better to send just a few that build excitement step by step. Have you noticed if teaser emails make people more eager to open your future messages?
