What a message costs
Texts and emails are passed through at cost, with nothing added. What actually drives the bill is length, and one emoji can triple it.

Most salon software sells you message credits. That model rewards whoever wrote the software for sending more messages than you needed, which is why we don't use it.

Passed through, with nothing added
Texts and emails are delivered by carriers, and carriers charge for them. You pay what they charge us — no markup, no bundles, no credits that expire at the end of the month. There's nothing here we make money on, which means nothing here has an incentive to grow.
The consequence worth knowing: messages aren't free, and no allowance quietly absorbs them. Sending a text to eight hundred clients costs eight hundred texts.
Length is the whole game
A text is billed in parts, and the number of parts depends on the characters in it:
| What's in the message | Characters in one part |
|---|---|
| Plain letters, numbers and basic punctuation | 160 — then parts of 153 |
| Anything else at all — an emoji, a curly quote, an accent outside the basic set | 70 — then parts of 67 |
That second row is the one that catches people. A reminder that fits in one text becomes three the moment somebody adds a smiley, because the whole message switches to the wider encoding — not just the emoji. A quote mark pasted in from a document does exactly the same thing without looking like it did anything.
Email doesn't work this way. Length barely matters, and a message costs a small fraction of a text either way.
What actually keeps it down
- Send by email where email will do. Receipts, newsletters, anything long.
- Keep marketing consent honest. A client who never agreed is a message you paid for and shouldn't have sent — see Consent, privacy and deleting someone.
- Narrow the audience. A campaign to the people it applies to beats a campaign to everyone; Choosing who gets it is where that's decided.
- Write short. Not for style — 160 characters is a real boundary and a second sentence can cross it.
Where to see what you've spent
Settings → Messaging usage — under Your plan, beside your AI allowance.
It shows the month so far: what your texts cost, what your emails cost, and — the number nobody has ever shown you — how many segments those texts came to. That last figure is the one to read. A month of 200 messages that came to 600 segments is a month where something in your wording is costing you triple, and the message count alone would never have told you.
Underneath it says what the total comes to as a share of what you pay for RewireBox. If your messaging starts approaching your subscription, the screen says so plainly rather than leaving you to meet the figure on a statement.
Common questions
Where do I see what I've spent?
Settings → Messaging usage, under Your plan. It shows this month's texts and emails, what each cost, and how many segments your texts came to — the figure that's actually charged.
Do you sell message credits?
No. Texts and emails go out through the carriers at what they charge us, with nothing added on top. There's no bundle to buy, nothing expiring at the end of the month, and no reason for us to want you to send more.
How long is one text?
160 characters, if every character is in the plain alphabet. Longer than that and it's sent in parts of 153 — so a 300-character message is two texts, not one.
Why would an emoji change anything?
A single emoji switches the whole message to the wide encoding, where one part holds 70 characters instead of 160. The same reminder can go from one text to three. Curly quotes pasted in from a document do it too.
Is email cheaper than texting?
By a lot, per message. Where either would do — a receipt, a newsletter, a long explanation — email is the cheap one.
Which messages count?
Every one that leaves the building: reminders, confirmations, campaigns, automations, replies you type in the inbox, and booking verification codes.
Can I see what I've spent?
Not yet — there's no screen for it. Every send is metered, but the total isn't shown to you today. The honest answer is that this article is the guidance and the number is coming.
