  "notes": "(price re-verified 2026-09-22 against the vendor's own pricing page; EVERY rate identical to the 31 Aug 2026 reading, to the cent) (2026) Postage is included in every per-piece rate. Three PURCHASABLE tiers: Starter is free and pay-as-you-go; Premium is $399/month billed annually or $449 month-to-month; Enterprise is custom-priced. On Starter, postcards are $0.76 (4x6), $0.79 (6x9), $0.85 (6x11) and $1.15 (11x18 tri-fold), and handwritten pieces are $1.56 (handwritten envelope with printed letter), $1.66 (handwritten postcard), $2.86 (card and envelope) and $3.11 (bi-fold card and envelope). Premium's card shows $0.54-$0.88 for postcards and $0.85-$1.71 for handwritten, Enterprise's $0.56-$0.88 and $0.81-$1.52 - but both are labelled 'as low as with spend commitment', so those floors need volume as well as the subscription. Handwritten insert media (a card with no envelope, shipped inside a package rather than mailed) is listed from $0.49 and is not offered on Starter. New accounts get $30 in free credit. FOURTH TIER, NOT PURCHASABLE FROM THIS PAGE (first recorded 22 Sep 2026): every comparison header reads 'Starter | Core | Premium | Enterprise', and Core carries a full rate column of its own - $0.61 (4x6), $0.68 (6x9), $0.75 (6x11), $0.98 (tri-fold), and handwritten $1.22 / $1.26 / $2.05 / $2.30, taken from the page's own core-*-m data attributes - while the price row above it holds only three cells (FREE, $449/$399, Custom Pricing). Core has no card, no button and no monthly fee anywhere on the page. VENDOR SELF-CONTRADICTION in the 'as low as' summaries: the Starter card sums its list up as 'Printed: $0.73 / Handwritten: $2.83' at the top of the page and as 'Printed: $0.76 / Handwritten: $2.86' lower down, while the list itself never goes below $0.76 / $2.86; the Enterprise column does the same ($0.53 / $1.24 against its own floor of $0.56 / $1.27). Only Premium's summary ($0.54 / $1.46) matches its rate list. Add-on rows publish two numbers and then 'Custom' without labelling which tier each column is: LeadReveal $0.50 and $0.25 per card, double-sided printing $0.12 and $0.07, NCOA address verification $0.03 and $0.025, data enrichment $0.20 and $0.12, custom mailing-list contacts $0.20 and $0.12. Also on the page: special discounts for 501(c)(3) organisations (separate nonprofit pricing page); a 'Powered by LettrLabs' white-label track for resellers and agencies at custom partner pricing, described as everything in Enterprise plus client sub-accounts and reseller billing; storm-triggered mailing powered by HailTrace, absent on Starter; and two Enterprise-column features still marked 'Coming Soon!' - A/B testing and third-party attribution via SearchLight.",
