Integrate ConvertKit to Lob in one click, or tell Integrately AI how you want each subscriber handled. Confirm subscriptions, verify postal addresses, and dispatch letters or postcards automatically.
Many businesses rely on marketing to bring in new customers and grow their sales. One key element of successful marketing is staying in touch with your prospective customers. However, manually sending out messages to each new contact can be time-consuming and ineffective. Fortunately, there is a better way.
By automatically sending a Lob message for every new ConvertKit subscriber, you can stay connected with your prospects without spending hours crafting individual messages. This simple automation can help you build better relationships with your prospects and close more sales.
