When you'd like to email a lead, you can email them from right within Lead Booster. Alternatively, if you've emailed the lead using another email program, you can record that email in Lead Booster.
Either way, you'll begin by opening the lead in the Lead Profile and then clicking the button. Upon clicking this button, you'll be presented with two options:
Email from Lead Booster — Choose this option to write an email to the lead within Lead Booster, and send it directly from the app.
Log External Email — This is where you can record an email you sent to the lead from outside of Lead Booster.
Both of these options will add an event to the lead's timeline in the Lead Profile.
