What one dedicated send likely costs
Our estimate, not a quote$790 to $5,950for one dedicated send
79,000 subscribers × $10 to $75 per 1,000 subscribers beehiiv, 29 May 2026 ↗
79,000 subscribers x $10 to $75 per 1,000 subscribers (beehiiv, 29 May 2026). This is our arithmetic on a published benchmark, not a quote from the creator.
Specialised B2B lists often command more (beehiiv quotes $50 to $100+).

What we checked, in full
21 checks, 11 passed, 1 to review
| ✓ | Metrics came from the platform | Every audience figure here is a value Substack's own API returned, never estimated or inferred. The price estimate is the one number we work out ourselves, and it is labelled and shows its arithmetic. | not published |
| ✓ | Enough recent posts to judge | 10 recent posts sampled (target 10). | not published |
| ✓ | Newsletter floor: ≥10,000 free subscribers and ≥20 median reactions | 79,000 free subscribers (Substack's own figure, not the author's claim), 44 median reactions across 10 recent issues. | required |
| – | Open rate | Nobody publishes a newsletter's open rate: not Substack, not the author. How many subscribers actually opened the email a sponsored slot sat in is unknown, and is not estimated here. The subscriber count is the size of the list, not the size of the audience. | not published |
| ✓ | A sponsored slot would reach the free list | 100% of recent issues go to the whole list, so a sponsored slot reaches the subscriber count shown. | integrity |
| ✓ | Tech / dev / software engineering | 8 distinct dev signals in the bio and post text: pipeline, coding, architecture, testing, claude, ai coding. | required |
| ✓ | Not a gaming channel | No gaming signal in the text. Substack publishes no content category, so this is a text judgement. | required |
| ✓ | Not a hardware / gear channel | No hardware/gear pattern. | preference |
| ! | Target region (US / UK / EU / AU / NZ / SG) | This account has left its location field empty. Region is unknown and must not be claimed. | required |
| ✓ | Reactions plausible for the subscriber count | 44 median reactions against 79,000 free subscribers (0.06%). | integrity |
| – | Average is not one viral outlier | No view counts on this platform. | not published |
| – | Comment volume matches the view counts | Comment counts were not returned for this account. | not published |
| – | Reach plausible for the audience count | No view counts on this platform. | not published |
| ✓ | Posted recently | Last post 14 day(s) ago. | preference |
| ✓ | Publishes on a regular schedule | Median 7.2 day(s) between posts; the 10 sampled posts span 174 days. | preference |
| – | Sampled posts are recent enough to compare | Too few dated posts with counts to test whether the sample is comparable. | not published |
| – | Same numbers from two endpoints of the same API | No post from this account appeared in both the search index and the profile feed, so there was nothing to cross-check. | not published |
| – | Verified against the platform's own published feed | Substack publishes no independent public feed to check the API's numbers against. YouTube is the only platform here where that second source exists. | not published |
| ✓ | An independent creator, not a company's own channel | Nothing marks this as a company-run channel: it is not a known company account, the name carries no corporate designation, and the bio is not written in a company's voice. | required |
| – | Same person confirmed on other platforms | No other public profile was linked from this account, so this record covers one platform only. | not published |
| – | Runs paid promotions (platform-declared) | Sponsorships shown for this creator are parsed from the text of their own post descriptions, so they are suspected rather than platform-confirmed. | not published |
