mass message

A mass message goes out to a list, not to a person. The platform copies the same text to every fan in the group you selected, and each copy lands in that fan’s private thread looking exactly like something typed for him. That is what makes the format awkward: it arrives in a one-to-one channel, so it is read as if a person wrote it there. The nearest neighbour is the message sequence, which also sends text written in advance, but a sequence fires per fan, on a clock that starts when he does something. A mass message fires once, for everybody, when you press send.

What does a mass message earn?

Volume, on the day. It is the only tool in the inbox that reaches a whole segment in one action, and it converts the fans already close to buying. That is real money, and it is why nobody stops sending them.

What it cannot do is build anything. A blast does not answer, does not adjust its price, and does not notice that the fan it just pitched declined the same offer four days ago. Our data is consistent about where sales actually come from: conversion climbs with the number of real exchanges and peaks after about ten, and pitching before the sixth message drops it by roughly a third. A mass message is message one, sent to people at every stage at once.

What does a mass message cost?

Unsubscribes. And they are invisible on the day. The fan who was going to renew does not write back to say the message annoyed him. He simply does not renew, weeks later, and the loss surfaces in churn with nothing attached to it.

Three costs, roughly in order of size:

• Non-renewals. The largest, and the hardest to attribute to any single send.
• Muted threads. A fan who stops opening your messages is gone before he cancels.
• Wasted pitches. Offering something a fan already owns, or already refused, spends credibility later.

Why does segmentation change the arithmetic?

Because the cost falls almost entirely on the people who should not have received the message, and segmentation is what removes them. The same text sent to a small relevant list and to the entire fanbase earns comparable amounts and costs very differently.

Sent to	What you get
Everyone	Highest reach, highest unsubscribes, lowest relevance
Recent buyers of a related item	Short list, strong conversion, little irritation
Fans who declined this exact offer	Nothing to gain: exclude them before sending
Expired fans	A different message altogether, not this one

Two habits cover most of it. Exclude before you include: strip out anyone who owns the item or has refused it, then look at who is left. And never send the same blast twice to the same list, on the theory that some of them missed it.

When should a mass message go out?

In the evening, and never in the small hours. Conversion collapses between 2am and 6am in our data and is at its highest in the evening, and a broadcast is the one send where you control the hour completely rather than answering whenever a fan happens to write.

Frequency is the other half of it. A narrow segment sent rarely keeps the list worth something; the same blast to everybody, often, is what empties it. And when a fan replies to a blast, the blast has finished its job: what follows is a conversation, not another broadcast. If he then goes quiet, the right next move is a follow-up written for him alone.
