Marc Lou Built a beehiiv Rival. SendFox Brought Popcorn.

The actual story.

Newsletter-platform beef now has a competitor working the concession stand. On October 20, Noah Kagan (@noahkagan) shared a boxing-style promotion casting beehiiv's Tyler Denk (@denk_tweets) against Marc Lou (@marclou), with SendFox watching from the sidelines. The punchline: "Less drama. Less cost. We're just eating popcorn." SendFox’s campaign

The spectator has something to sell. Kagan, AppSumo's founder, lists SendFox among the businesses he started. SendFox has even built a landing page specifically courting Marc, explaining that the invitation is no endorsement from him. Apparently, somebody else's customer complaint can become your marketing campaign. Kagan's biography · SendFox's pitch to Marc

On October 9, Lou said beehiiv's rising prices had prompted him to build his own newsletter platform with AI. He subsequently open-sourced MailCheap, then launched its hosted version on October 15. His complaints about his bills remain his account, rather than independently verified billing history. Lou's account · MailCheap's launch

Denk answered with a long inventory of what running a newsletter platform entails. His October 20 essay defended the continuing work behind maintenance, security, deliverability, support and monetization. It also turned personal. The useful question survives without the insults: which costs does a cheaper tool eliminate, and which responsibilities move elsewhere? Denk's essay

News beyond the meme

The business behind the beef is substantial. beehiiv reports $19 million in publishers’ paid-subscription revenue during 2025. Kit advertises more than 550,000 creator business owners, while SendFox reported sending over 35 million emails monthly in a June 9, 2026 update. These company-reported figures measure different things, not a winner. But they explain why this fight reaches beyond a cheaper send button: platforms are competing for the infrastructure behind creator businesses. beehiiv’s report · Kit · SendFox’s update

For a weekly writer, start with sending volume. MailCheap's $19 monthly Starter plan includes 20,000 emails. Its advertised 83% saving is pegged to a particular comparison: 4,000 subscribers receiving one email a week. That's a vendor's scenario, not a blanket discount. Check the billing period, subscriber allowance and features your publication actually needs. MailCheap's pricing and footnote

For a daily publisher, run the numbers again. Hypothetically, 4,000 readers receiving 30 issues require 120,000 emails, before welcome messages or tests. That exceeds the same MailCheap starter allowance. beehiiv says all its plans include unlimited sends, making frequency an important part of the comparison. A weekly newsletter and a daily publication can have identical lists and very different workloads. beehiiv's pricing

For a creator selling courses, subscriptions or sponsorships, include the tools that help produce revenue. The wider market includes Kit, led by founder and CEO Nathan Barry (@nathanbarry), with email, automations, commerce and recommendation tools. Check the plan needed for your sales workflow, the tools it replaces and the work required to move. Kit's plans · Kit's team

The popcorn seller deserves the same scrutiny. SendFox's $29 Lifetime offer for new purchases includes 5,000 contacts and a one-time pool of 300,000 sends. That pool never refreshes; continuing after it is exhausted requires a Pro subscription. Its page courting Marc also warns that switching means rebuilding forms and automations and checking paid-newsletter or ad-network workflows separately. Lifetime allowance · Migration caveats

Finally, distinguish self-hosting from buying a hosted service. Lou's launch replies say hosted MailCheap uses PostShiba, while the original self-hosted project used Amazon SES. Buying MailCheap does not automatically mean personally maintaining every component. Lou's launch and replies

Our take: price the newsletter you actually run, including the features you use, the migration work and the maintenance you accept. The founders can fight over the trophy. Your next issue still needs to reach readers.
