Who is Lob + Viral Loops integration for?
Marketers, growth managers, and operations teams managing referral programs can automate physical mail fulfillment and keep rewards tracking accurate without manual spreadsheets.
Growth marketers
Operations managers
Agency account managers
eCommerce fulfillment teams
Customer success leads
Finance coordinators
📈
Growth marketers
You are tracking referral acquisition metrics in campaigns, but your tracking sheet only updates when someone manually exports participant data, so the conversion counts you review are always outdated — this integration means every new participant triggers mailings and logs data instantly so your metrics stay current.
⚡
Operations managers
You manage physical reward mailings and address verification for referral winners, but manual processing causes shipping delays and customer complaints — this integration means address validation and letter dispatch happen automatically the moment a milestone is reached.
🤝
Agency account managers
You report on client referral program performance, but keeping clients updated on physical reward shipments requires constant manual checks across systems — automating both apps means client reports reflect real-time mailing statuses without extra effort.
📦
eCommerce fulfillment teams
You handle high volumes of referral reward redemptions, but manual entry leads to transcription errors and delayed shipments — automating both apps means reward redemptions immediately generate verified postal orders in Lob.
🎯
Customer success leads
You rely on upstream referral notifications to send onboarding gifts to advocates, but delays leave advocates waiting too long for their welcome kits — connecting these apps means welcome letters dispatch the second a participant registers.
📊
Finance coordinators
You audit referral campaign costs and shipping expenses, but missing records in your finance logs cause monthly reconciliation gaps — this integration means every mailing and reward redemption is logged reliably across your connected tools.
