Reply + Lob Integration

Send Lob message for new Reply contact

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 Reply contact, 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.

Marketing analysts
You're tracking outreach replies in Reply but your reporting dashboard only updates when someone manually exports campaign results, so the conversion counts you're reviewing are always a few hours behind — this integration means every reply triggers immediate physical mail and your data stays current.
⚡
Sales development reps
You're managing active sequences in Reply but leads that request physical collateral get buried in your inbox before anyone prints them, so prospects wait days for follow-up mail — connecting these apps means every new contact instantly dispatches a letter and your response times drop.
🤝
Account executives
You're sending outreach campaigns through Reply and need to show clients physical mail touchpoints, but manual tracking leaves gaps in your client reports — automating both apps means every postcard send is logged automatically and your audit trails are complete.
📦
Outreach coordinators
You're scaling outbound volume in Reply and manually addressing mailers for interested prospects, so team members spend hours on post office runs instead of selling — with this integration, every interested lead triggers automated physical mail delivery and your outreach scales without extra headcount.
🔄
Business development managers
You're qualifying prospects in Reply and waiting for manual handoffs before sending welcome kits, so downstream mailing steps stall in the queue — automating both apps means every campaign transition triggers instant mail fulfillment and your pipeline moves smoothly.
📋
Sales operations specialists
You're logging outreach touchpoints in Reply but physical mail records live in a separate spreadsheet with missing delivery dates, so your historical logs have gaps — connecting these apps means every mailer verification is recorded cleanly and your contact history remains unified.
