Email Strategy by Auction Phase

Pre-sale (marketing and bidder acquisition)

Email type Timing Content Goal
Sale announcement 30-45 days before sale "[Auction company] presents: [Sale title / Estate name / Equipment description]. [Date]; [location or online platform]; [preview dates]; [highlights]. [View catalogue / Register to bid]" Awareness; early bidder registration
Catalogue / lot alert 14-21 days before sale "Now online: [X] lots in [category]. Highlights: [featured lots with images and estimates]. [View full catalogue]; [Register to bid]; [Set lot alerts]" Catalogue engagement; targeted bidder interest
Category-specific alert 14-21 days before sale "New [category] lots: [specific items matching subscriber's interest]. [View lots]; [Set bid alerts]" Personalised lot discovery; targeted engagement
Preview / inspection reminder 3-7 days before sale "Preview [Sale title]: [dates]; [times]; [location]. Inspect lots in person before bidding. [Preview highlights]; [Catalogue link]" Preview attendance; bidder confidence
Registration deadline 3-5 days before sale "Register to bid by [deadline]: [Sale title]; [date]; [how to register]; [deposit requirements]; [terms]" Bidder registration completion

During sale (active bidding)

Email type Trigger Content Goal
Outbid notification When outbid on watched lot "You have been outbid on Lot [number]: [description]. Current bid: $[amount]. [Increase your bid]; [View lot]" Re-engagement; higher bids
Lot closing soon 30-60 minutes before lot closes (timed online) "Lots closing soon: [lot numbers and descriptions]. [Place final bids]; [View all closing lots]" Last-minute bidding activity
Winning bid confirmation Immediately after hammer falls "Congratulations. You are the winning bidder on Lot [number]: [description]. Hammer price: $[amount]. [Buyer's premium: X%]. [Total: $amount]. [Payment instructions]; [Pickup/shipping details]" Payment collection; logistics

Post-sale (settlement and retention)

Email type Timing Content Goal
Invoice Within 24 hours of sale "Your invoice for [Sale title]: [lots won]; [hammer prices]; [buyer's premium]; [taxes]; [total due]. [Payment methods]; [payment deadline]; [pickup/shipping information]" Payment collection
Payment reminder 3 and 7 days after sale if unpaid "Payment reminder for [Sale title]: [total due: $amount]. [Payment deadline]; [late payment policy]; [Pay now link]" Payment collection; reduce defaults

Consignor communication

Email type Timing Content Goal
Consignment invitation Ongoing "Considering selling [category]? [Auction company] achieves strong results: [recent comparable sales]; [commission structure]; [free appraisal offer]. [Request appraisal]" Consignor acquisition
Consignment confirmation After agreement signed "Your consignment for [Sale title]: [lot numbers]; [descriptions]; [estimates]; [reserves]; [sale date]; [commission terms]. [View your lots online]" Consignor information; confidence
Pre-sale update to consignor 7 days before sale "Your lots in [Sale title]: [registered bidders]; [lot views]; [interest indicators]; [sale date reminder]" Consignor confidence; transparency

Building Auction Email Lists

When consolidating bidder and consignor data from auction management software (Auction Flex, HiBid, LiveAuctioneers, Invaluable -- CSV), payment processing records, shipping platform data, website registration forms, on-site sign-in sheets, mailing list subscribers, consignor databases, and partner referral lists, upload the files to Email Extractor to extract and deduplicate email addresses across all sources. Auction participants interact through online registration, in-person sign-in, bidding, invoicing, payment and shipping, and the same buyer who registered online, signed in at the preview, bid in the auction, received an invoice and arranged shipping appears in five different systems, so deduplication ensures each participant receives one consistent set of communications.
