# Maximizing engagement To maximize engagement with your direct mail campaigns, we recommend leveraging dynamic personalization and integrating clear calls to action (CTAs) on each mailpiece. Including a coupon code, phone number, URL, or QR code is a powerful way to bridge the gap between offline and online experiences, driving more interaction with your brand. Lob also empowers you to enhance your direct mail campaigns by leveraging USPS’s Informed Delivery service to create an additional digital touchpoint, giving your audience another opportunity to engage with your content before they even receive the physical mail. * [Dynamic personalization](/print-and-mail/designing-mail-creatives/maximizing-engagement/dynamic-personalization.md) * [Adding QR codes](/print-and-mail/designing-mail-creatives/maximizing-engagement/adding-qr-codes.md) * [URL shortener ](/print-and-mail/designing-mail-creatives/maximizing-engagement/short-urls.md) * [Informed Delivery](/print-and-mail/designing-mail-creatives/maximizing-engagement/informed-delivery.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
