Warmup pricing comparison
Side-by-side TCO framing at common inbox counts using publicly stated merchant pricing. List price doesn’t mean better inbox placement.
TCO methodology
- Sources: Merchant public pricing URLs only. Each filled cell cites the source page and is stamped verified 2026-10-26 when captured.
- Inbox columns: We map list prices to editorial inbox counts (5 / 20 / 50) when the vendor sells by inbox or publishes “best suited” inbox hints. When the vendor sells by daily volume, seats, or credits, we say so and avoid fake per-inbox math.
- Yearly vs monthly: When a page shows both, we list both. Yearly figures are usually “per month equivalent billed annually,” not a separate product.
- Not listed publicly: Used when there is no clear self-serve list price for that scale (e.g. Warmbox Team/custom beyond 6 inboxes). We do not invent quotes.
- Out of scope for TCO cells: Taxes, payment processing fees, sales discounts, credit burn, domains, and inbox hosting. Those can dominate real spend.
- Not a ranking: Lower list price ≠ better placement. Full label rules: methodology.
Apples-to-oranges caveats
- Warmbox = inbox-tier warm-up SKU (1 / 3 / 6 / custom).
- TrulyInbox = daily warm-up volume shared across unlimited paid-plan accounts; vendor “best suited” inbox counts are sizing hints, not hard caps.
- Folderly Email Warm-Up = linear per-mailbox at published yearly rate; Insights / Pulse are separate products on the same pricing URL.
- GlockApps Bundle = diagnostics (spam-test credits + DMARC analytics etc.), not warm-up inboxes.
- Instantly / Lemlist = bundled outreach + included warm-up; priced by emails/contacts (Instantly) or email volume / per-user Multichannel (Lemlist), not warm-up mailbox tiers.

Per-merchant notes
- Warmbox: Public Solo/Start-up/Growth cards stop at 6 inboxes. Larger fleets require Team/custom chat quotes — we show that as custom quote rather than inventing a list price.
- TrulyInbox: Volume is shared across connected accounts. Vendor publishes warmup ratio guidance (e.g. 2:1 warmup:cold framing on their pricing page) — treat as vendor education, not our performance claim.
- Folderly: Published warm-up rate is linear; demo/sales flows may change effective price. Insights Free/Monthly/Yearly and Pulse free monitoring are separate SKUs.
- GlockApps: Compare on credits/users/DMARC message caps, not inbox count. Complementary to warm-up purchases.
- Instantly / Lemlist: See Instantly vs Lemlist for who-for and scenario TCO. Also read when bundled warm-up is enough before stacking standalone warm-up.
