Which strategy is NOT effective in growing an email list?

Restricting sign-up forms is not an effective strategy for growing an email list because it limits accessibility for potential subscribers. When sign-up forms are overly restrictive, either by requiring too much information upfront or by being placed in hard-to-find locations on a website, it discourages users from subscribing. Successful email list growth typically relies on making it easy and attractive for users to join.

In contrast, effective strategies such as offering lead magnets, using social media promotions, and integrating sign-ups with the website actively encourage more users to subscribe. Lead magnets provide an incentive, social media promotions broaden reach and visibility, and website integration ensures that users have multiple, convenient opportunities to sign up. All these methods prioritize user engagement and optimize the subscription process.
