How ReplyLead sources its numbers
Updated September 9, 2026 · ReplyLead editorial standards
The short answer: ReplyLead publishes first-party operational research and source-based guides. Figures should identify their population, period, denominator and limitations. Public provider offers are evidence of the offer, not independent verification of results. Our calculators use explicitly labeled assumptions where actual buyer outcomes are unavailable.
Cold email is a channel full of unverifiable claims. This page explains who writes replylead.com, where its figures come from, what we refuse to publish, and how to get an error fixed.
Who writes this site
ReplyLead is responsible for the material it publishes. Mark Glazer is the founder and contact for corrections; his background is on the about page. Research and editing may use software assistance. A publisher byline does not imply an independent audit or first-hand testing of every compared provider.
Where the numbers come from
First-party campaign operations. Operational datasets and client-reported accounts have different scopes. The case studies identify attribution and available evidence. Replies, sales-qualified leads, booked meetings, held meetings and accepted opportunities must be reported separately; one stage does not establish another.
The published fee table. The technology cost table in the ROI calculator is built line by line at verified list prices from each vendor, not rounded from memory.
Live verification before every send. Every list is re-verified with a live email-verification pass immediately before sending. Vendor "verified" flags are not trusted: in one of our own audits, 35 of 35 dead mailboxes behind a bounce spike traced back to leads whose vendor validation said valid.
Year-stamped figures. Numbers that age, such as reply rates and thresholds, live on the cold email benchmarks page and carry the year they were current.
The campaign-book research. The reply-rate work published on what a realistic cold email reply rate is and the distribution behind the average is drawn from our own campaign book, not a survey and not a vendor sample. Its method, and the rules we apply before a campaign is eligible to count, are written up on the methodology page.
Every figure names its base. One dataset produces several defensible answers, so a number here is meaningless without the denominator attached to it. Replies per contacted lead and replies per email sent are different measures of the same campaigns. A pooled rate across every campaign and a median campaign rate answer different questions. Some figures are computed across the whole book and others only across campaigns that clear a minimum contacted-lead threshold, because a rate from a tiny campaign is noise. Wherever a figure appears on this site, the base it was computed on is stated beside it - and if you ever find one that is not, that is a reportable error under the corrections policy below.
What we do not do
No invented statistics. If a figure is not our own operating data or a named published source, the sentence is written without a number. External numbers name their source in the sentence, every time.
No pay-to-play rankings. Our comparison lists accept no payment for placement. One disclosure worth repeating: ReplyLead publishes those lists and appears first in them. The rest of each list is real competitors described from their own published materials, with no star ratings and no invented review counts.
Corrections
Found something wrong? Email Mark@ReplyLead.com. We check the claim against the underlying campaign data or the named source, correct the page, and restamp its visible Updated date.
Update cadence
When substantive content changes, the editorial standard is to update the visible date and relevant structured data together. Dates should describe actual revisions, not imply that every source or commercial offer was independently reverified. Use the corrections address above to report a stale source or inconsistent date.
Common questions
Who writes ReplyLead's guides?
ReplyLead publishes the guides, with Mark Glazer as the founder and corrections contact. Research and editing may use software assistance. Authorship identifies responsibility; it does not establish independent validation of every statement.
Where do ReplyLead's statistics come from?
First-party campaign operations, portal-tracked client funnels, and a fee table built at verified list prices. Anything external names its source in the sentence.
Does ReplyLead accept payment for placement on its comparison lists?
No. ReplyLead publishes those lists and appears first in them, disclosed on each list; the remaining entries are described from their own published materials.
How do I report an error on replylead.com?
Email Mark@ReplyLead.com. The claim gets checked, the page gets corrected, and the Updated date gets restamped.
How do I know when a page was last updated?
Look for the Updated line under the title. It moves only when the content does.
Judge the numbers against the work
The case studies distinguish client-reported accounts from operator aggregates and explain available evidence. Review those limits before using an example in a buying decision.
