Four reliable and effective lead generation strategies are -
Chatbot conversations - You can’t always dedicate time and effort to lead generation. But chatbots can! They are available 24*7 building your brand’s rapport with the users.
Value-packed newsletter - A value-packed newsletter acts as a lead magnet. It attracts prospects and keeps them connected to you. You can stay on top of the minds of your users with weekly or daily newsletters.
Freemium product or free trial -  Offering free products or services attracts those prospects who aren’t ready to buy. By offering free trials, you can convert them into paying customers for paid features.
Retargeting - Don’t lose hope if prospects don’t get converted during their first interaction. Use retargeting and reach out to them again by various means.
