問題文
A software company sees that new subscribers who receive nothing for several weeks after signing up later show very low engagement. The team wants to raise early engagement without adding a promotional send. What should it introduce?
選択肢
- A sunset policy that stops mailing subscribers who have not opened for six months, so the relationship begins while interest is still high.
- A re-engagement campaign that starts once a subscriber has been inactive for a year, so the relationship begins while interest is still high.
- A quarterly digest that starts three months after signup and repeats the newest offers of that season, so the relationship begins while interest is still high.
- A welcome series that starts right after signup and explains what the subscriber will receive, so the relationship begins while interest is still high.
