In your welcome sequence survey, ask subscribers "who else they follow" in your niche. This question provides direct voice-of-customer research. If multiple new subscribers name the same influencer or publication, it signals a high-potential new source for targeted acquisition efforts and partnerships.
A late-sequence email explicitly inviting subscribers to unsubscribe may seem counterproductive, but it acts as a powerful filter. Those who remain are more invested, leading to higher long-term engagement and fewer spam complaints. This weeds out subscribers who would have disengaged later anyway.
Email providers heavily weigh engagement signals (replies, opens, clicks) within the first week of a new subscription. This initial "probation period" has a disproportionate impact on your long-term sender reputation and deliverability. A welcome sequence should be engineered to maximize these signals in a compressed timeframe.
The first email in a welcome sequence should be a short, plain-text message from an assistant, not the founder. Its sole purpose is to get a reply, which whitelists your address in services like Gmail and Yahoo, guaranteeing future inbox placement before the main welcome email even arrives.
