Section Content
Subject line "Commercial plumbing sub for [GC company name] projects"
Opening "[First name], [Company name] is a licensed commercial plumbing contractor in [state(s)] serving general contractors on projects from [X] sq ft to [X] sq ft. If you need a plumbing sub that: [bids accurately from plans (not a number pulled from the air)]; [shows up when scheduled (your schedule, not ours)]; [coordinates with other mechanical trades (HVAC, electrical, fire protection) without conflict]; [passes inspection the first time]; [handles punch list within [X] days]; [carries $[X]M in liability insurance]; [is bonded for projects up to $[X]], we should be on your bid list..."
Value "What we do: [commercial plumbing (all fixtures, supply, waste, vent)]; [fire sprinkler systems (NICET-certified designers; licensed installers)]; [medical gas systems (ASSE 6010/6020/6030 certified)]; [hydronic piping]; [process piping]; [underground utilities (water, sewer, storm)]; [fixture procurement and installation]. Our team: [X] licensed plumbers; [X] apprentices; [average [X] years experience]; [OSHA 10/30]; [confined space certified]; [union / non-union as applicable].

CTA "Would bid list inclusion be useful? I can send our qualifications package, reference list and current insurance certificates: [reply / phone]"

To property manager (service contract)

Section Content
Subject line "Plumbing maintenance programme for [Property name / portfolio]"
Opening "[First name], plumbing problems at [Property name] cost more than the repair: [tenant disruption and complaints]; [water damage to finishes, equipment and tenant property]; [emergency service premiums (after-hours rates are [X]-[X]x standard rates)]; [insurance claims and deductibles]; [code violations from deferred maintenance]. A preventive maintenance programme catches problems before they become emergencies..."
Value "Our commercial plumbing maintenance programme: [quarterly inspection of all plumbing systems]; [water heater inspection and maintenance]; [backflow prevention device testing (annual, as required by your water utility)]; [grease trap pumping schedule (if applicable)]; [drain cleaning and jetting (preventive, not reactive)]; [fixture inspection and repair]; [water pressure monitoring]; [leak detection inspection]; [detailed inspection reports with photos and recommendations]; [priority emergency response for programme members ([X]-hour response vs. [X]-hour standard)]; [no after-hours premium for programme members]. Programme cost: $[X]-$[X]/month per property (depends on property size and system age). Average programme member saves $[X]/year in avoided emergency repairs"

To restaurant owner (grease trap and kitchen plumbing)

Section Content
Subject line "Grease trap service and kitchen plumbing for [Restaurant name]"
Opening "[First name], your grease trap at [Restaurant name] is a health department compliance requirement and an operational necessity. If it fails (backs up, overflows, is not pumped on schedule), you face: [health department violation (can result in closure)]; [sewer backup into your kitchen]; [foul odours in dining area]; [environmental violation (grease discharge to municipal sewer)]; [fines ($[X]-$[X] per violation in [city/county])]. If your current grease trap service is unreliable (missed pumpings, incomplete cleaning, no documentation, no manifest), you are at risk..."
Value "Our restaurant plumbing programme: [grease trap pumping on your schedule (weekly, biweekly, monthly -- based on your volume and trap size)]; [complete trap cleaning (walls, baffles, inlet, outlet -- not just skimming the top)]; [manifested disposal at licensed facility (documentation for health department)]; [grease trap inspection and condition report]; [kitchen drain maintenance (grease buildup in lines is the number one cause of kitchen drain backups)]; [emergency response (drain backup during service = same-day response)]; [health department compliance documentation (pumping records, manifests, inspection reports)]. Pricing: $[X]-$[X] per pumping (based on trap size); monthly programme: $[X]-$[X]/month (includes [X] pumpings, drain maintenance, documentation)"

Data Sources for Prospect Lists

Source What you find Best for
General contractor directories (AGC, ABC, state licensing) Licensed GCs by location and project type GC subcontractor relationship building
Property management directories (IREM, BOMA, NARPM) Property managers by portfolio and location Service contract prospecting
Restaurant databases (health department, Google, Yelp) Restaurants by location, type and grease trap compliance status Grease trap service prospecting
Building permit databases New construction and renovation permits New construction plumbing bidding
Healthcare facility directories (AHA, CMS) Hospitals and healthcare facilities Medical gas and healthcare plumbing prospecting
School district directories (state education departments) School districts by size and location School plumbing maintenance prospecting
Water utility backflow testing databases Properties with backflow devices requiring annual testing Backflow testing service prospecting

When compiling prospect data from GC directories (HTML), property management directories (HTML), restaurant databases (CSV, HTML), building permit databases (HTML), healthcare facility directories (CSV, HTML), school district directories (HTML), water utility databases (HTML, CSV) and fire marshal databases (HTML), upload all files to Email Extractor to extract and deduplicate email addresses. Property managers, facility directors, restaurant owners and GCs appear across licensing databases, industry directories, permit filings and utility records, so deduplication prevents duplicate outreach.
