An autoresponder is a computer program that generates a response to an email, request, or action. Autoresponders were initially used to notify a sender of an undeliverable email, but now they are often used in email marketing. Autoresponders can give you the ability to send a customer a pre-written email when a specified event takes place, such as a customer creating an account or purchasing a product.

ROI is probably the most important metric in lead generation. The calculation is fairly simple: it’s the profit or loss you make from investing in a lead, compared against your initial investment. Let’s say you spent $15 capturing each lead, and a lead is worth $20 to you. Your profit from a lead ($5) against your initial investment ($15) gives you an ROI of 33%.
When a subscriber is sorted into a segment, it can trigger an automation to send to them. Each person’s interactions with your email campaigns or your website can trigger a sequence of follow-up emails based on their interests, allowing you to hone your message to your targeted audience. For example, if someone visits your pricing page, you know they’re probably further down your sales funnel and will want to follow-up appropriately. Or if they went to a specific product page or clicked on a link for that product, you can send additional information about the product, testimonials and more.
