About

HubSpot workflow app for formatting and verifying phone numbers. Format Phone Number (free, unlimited) standardizes numbers across 245 countries into E.164, international, national, digits-only, and RFC3966 formats. HLR Lookup confirms whether a phone is actually switched on and connected to a mobile network by querying the Home Location Register in real-time. Automatically populates HLR status, syntax check, and formatted number properties.

Clean Dial sits inside HubSpot as two workflow actions and a bulk verification service, built to address one specific gap: phone numbers in CRMs rot. Around 20% of contact phone data is unreachable at any given moment, and HubSpot's native formatting only handles US standards. If you run global outreach, the rest is on you.

The free side does formatting. Drop a phone number from any of 245 countries into the workflow action and Clean Dial outputs five formats simultaneously: E.164 for APIs, International for human-readable display, National for country-local conventions, digits-only for deduplication, and RFC3966 for click-to-call. The action also flags syntax errors so bad data doesn't slip through to a call queue or SMS campaign.

The premium side does live check via HLR (Home Location Register) lookup. This pings the carrier network in real time and returns whether a number is LIVE, DEAD, ABSENT_SUBSCRIBER, etc. It also returns carrier info, line type (mobile vs landline), and a 0 to 100 confidence score. Eleven custom contact properties get written back to each record so segmentation and routing can act on the verification data immediately.

I built this as my first solo HubSpot app for Daeda Tech's portfolio. It was mainly so I could get comfortable with building in HubSpot.

Auto Associations Pro

I helped develop this HubSpot app that automatically creates associations between CRM records based on custom rules. We designed it to eliminate manual linking and reduce data fragmentation. Our custom rules define logic like 'associate all Contacts from Companies to Deals'.

HubSpot app that eliminates messy CRM data caused by manual text inputs. Scans your unique record values and lets you flip a switch to turn any text property into a dropdown - no more 'New York' vs 'NYC'. Works across contacts, companies, deals, and tickets.
