Send Lob message for new ConvertKit subscriber

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.

Performance marketers
You're running email campaigns in ConvertKit but your direct mail tracking sheet only updates when someone manually exports lists, so the mailing metrics you're optimising against are always a few hours behind — with this integration, every subscriber action syncs instantly and your campaign data stays current.
Sales development reps
You need to dispatch physical outreach the moment a lead engages with your ConvertKit sequence, but manual address verification slows you down so high-value prospects receive materials too late — with this integration, verified letters and postcards dispatch automatically without delay.
🤝
Client success managers
You answer to clients who want immediate proof that onboarding letters and welcome packets have been mailed following email signups, but manual tracking leaves gaps in your reports — with this integration, every offline mailer is recorded the second it triggers.
⚙️
Operations teams
The volume of new subscriber addresses coming from ConvertKit is too high for your team to process and verify by hand, leading to constant mailing errors — with this integration, address verification and Lob dispatches happen at scale without manual intervention.
📦
Fulfillment coordinators
You own the physical mailing step and depend on upstream ConvertKit triggers to hand over customer shipping details, but delayed exports cause fulfillment bottlenecks — with this integration, order data flows seamlessly into Lob the moment subscribers confirm.
📊
Finance and admin teams
You need a reliable audit trail of every physical invoice and letter mailed to ConvertKit subscribers, but manual recordkeeping keeps missing transactions — with this integration, every mail dispatch is logged accurately with zero gaps.
