One Year of Inbox Senders Club: 137 Videos, 551 Hours, Zero Spam Complaints

On October 28, 2025, we uploaded a song about email deliverability to YouTube and waited to see whether anyone on Earth wanted that.

It turns out a few of you did.

One year later, Inbox Senders Club is a catalog of parodies and originals covering authentication, reputation, spam traps, bounces, unsubscribes and the rest of the inbox — in rap, metal, grunge, pop, funk, psych rock and blues. This is the year in numbers, the songs you played most, and what we kept coming back to.

The year in numbers

Metric	Year one
Total views	21,209
Watch time	551+ hours
Shares	271
New subscribers	+109
Videos published	137 (134 full-length, 3 Shorts)
Total runtime	9 h 23 min 20 s

Two of those numbers matter most to us.

551 hours of listening. That's more than three straight weeks of people choosing to hear about SPF alignment and complaint rates set to music. For a niche this narrow, it's an absurd amount of attention, and we don't take it lightly.

271 shares. Views are passive. A share is someone sending a song about suppression lists to a colleague, a client or a deliverability Slack channel and saying "you need to hear this." That's how a niche channel grows, and it's how most of you found us.

Year one's top hits

The five songs deliverability people played most:

• Reputation Love — 2Pac feat. Dr. Dre, "California Love" — 1,965 views
• Doing Something Unholy — Sam Smith & Kim Petras, "Unholy" — 1,125 views
• Say Your Name — Destiny's Child, "Say My Name" — 1,016 views
• Safe Sender — Destiny's Child, "Survivor" — 938 views
• Sabotage (Rap Rock Version) — Beastie Boys, "Sabotage" — 783 views

No surprise that a West Coast anthem about sender reputation took first place. Reputation is the one thing every sender is graded on and nobody fully controls, so it makes sense that it hit a nerve. Destiny's Child placing twice in the top five was a surprise, though. Apparently the identity questions in "Say My Name" and the endurance in "Survivor" both translate well to email.

What we kept singing about

Looking back across the catalog, the same handful of fights came up over and over, whatever the genre.

Authentication and sender reputation. From the G-funk of Reputation Love to Still SPF to DKIM2, our original about the next generation of DKIM. Proving who you are and earning trust over time is the foundation of everything else, so we wrote about it more than anything else.

The traps and blunders. Spam Trap Daze turned the silent damage of a trap hit into a Hendrix-style fuzz haze. One Click Goodbye argued for making it easy to leave. The Number of the Bounce gave bounce handling the full Iron Maiden treatment. None of these mistakes announce themselves, which is why they deserved a song each.

The calendar. Peak season gets its own soundtrack. Supermassive Black Friday and Paint It Black Friday kicked off our Black Friday series, built around the idea that your Q4 inbox placement is decided months before the sale starts.

The concept album. The Postmaster, released in May 2026: ten tracks, each mapped to one of Gmail's top sender issues, each in a different sonic world.

Four albums on streaming platforms

The YouTube channel came first, but year one also produced four full albums, all available on Spotify, Apple Music, Deezer and YouTube Music:

• Straight Outta the Inbox (December 2025): twenty-four originals about the art and anxiety of deliverability.
• Inbox on the Line (January 2026): twelve blues tracks on the grief and hard-won wisdom of the inbox.
• Click Through (May 2026): a funk story about Marcus Deliverino, a new marketer who declares war on the Promotions tab.
• The Postmaster (May 2026): the judge, the ten violations, the verdict.

The cadence

137 videos in twelve months works out to 11 or 12 a month, almost three a week, for a full year. We covered rap, metal, grunge, pop, funk, blues, psych rock and more. The genre changes every time. The rule doesn't: each song has to teach one real thing about getting mail delivered, and every song page backs up the lyrics with production notes and best practices you can apply.

That's the deal we're keeping for year two.

Thank you

To the 109 people who subscribed this year, to everyone who shared a song with a colleague, and to the deliverability people who told us a lyric finally made something click: thank you. You're the club.

Year two starts now. If there's a deliverability topic you think deserves a song, tell us. If you want new songs in your inbox (properly authenticated, we promise), the newsletter is on the homepage.
