People expect instant gratification, so waiting for a few hours or days before delivering is a no-no.
You look bad → their first impression of you is poor → they don’t trust you → don’t engage → never buy from you.
This means you need to use an email marketing tool / ESP (email service provider) to automatically do this for you.
Otherwise you’d need to be vigilant 24/7 and always be aware that someone has just opted-in and that you need to immediately deliver the lead magnet.
To technically “capture” subscribers’ email addresses and then instantly deliver your lead magnet via automated email messages, simply use the opt-in form and sequence capabilities provided by your email marketing tool.
If you’re not yet using one, why not give my email marketing tool - BirdSend - a risk-free try? We offer a free trial. If you’re not satisfied for any reason, simply cancel the trial.
If you’re already using one, BirdSend saves you 3 - 5X in expenses every month while still providing high email open rates. We also provide a free migration service to move everything from your current provider to us.
