Somewhere past 50,000 segments a month, your rate on Ready drops on its own — from $0.02 to $0.016 per segment, no plan to pick, no form to fill out. That's the Growth tier, and for a lot of scaled senders it's the end of the pricing conversation.
But once you're routing hundreds of thousands of segments, the question changes. At some point people start wondering whether they should call the deal desk and negotiate something custom. Sometimes that's the right move. More often — honestly — it isn't yet, and you'd be trading real time for a discount that doesn't move your P&L.
Full disclosure: I work for Ready. So take the framework below as coming from someone who benefits when you send more, but who'd rather you stay because the math actually works than because you didn't check it.
First, understand what the Growth drop already gives you
The Growth rate isn't a consolation prize. It's automatic, it applies the moment you cross 50,000 segments in a calendar month, and it's a real 20% cut on the per-segment portion.
Here's the part people get wrong: it's a blended rate, not a flat one. The first 50,000 segments in the month still bill at Standard. Only the segments past 50,000 get the lower rate.
| Monthly segments | First 50K @ $0.02 | Remainder @ $0.016 | Segment cost | Blended per-seg |
|---|---|---|---|---|
| 50,000 | $1,000 | $0 | $1,000 | $0.0200 |
| 80,000 | $1,000 | $480 | $1,480 | $0.0185 |
| 150,000 | $1,000 | $1,600 | $2,600 | $0.0173 |
| 300,000 | $1,000 | $4,000 | $5,000 | $0.0167 |
| 500,000 | $1,000 | $7,200 | $8,200 | $0.0164 |
(Carrier pass-through of $0.0045/segment sits on top of all of these, itemized separately — it isn't marked up and doesn't change with tier.)
Notice the curve flattens. At 300K you're at a blended $0.0167; doubling to 500K only pulls you to $0.0164. The marginal segment is already at $0.016 — the blend just approaches it asymptotically. That matters for the Enterprise decision, because the thing you'd be negotiating down is that $0.016 floor, and the higher your volume, the closer your blend already is to it.
If you want the full derivation of the blended number, we walked through it in At 80,000 Segments a Month, Your Blended Rate Isn't $0.016.
The threshold question, framed honestly
There is no public Enterprise number and I'm not going to invent one — it's negotiated per account by the deal desk. So the honest way to think about this isn't "at X segments Enterprise beats Growth." It's: is the size of the pool you'd be discounting large enough that a few tenths of a cent is worth a negotiation, a contract, and probably a commitment?
Work the sensitivity. Suppose a custom rate shaved $0.001 off your marginal segment (from $0.016 to $0.015 — illustrative, not a quote):
- At 150,000 segments/mo, the discounted pool is 100,000 segments. $0.001 × 100,000 = $100/mo.
- At 500,000 segments/mo, the pool is 450,000. $0.001 × 450,000 = $450/mo.
- At 1,000,000 segments/mo, the pool is 950,000. $0.001 × 950,000 = $950/mo.
$100/mo is not worth a procurement cycle. $950/mo, sustained, starts to be. That's the shape of the decision: the value of a custom rate scales with volume, and below roughly a few hundred thousand consistent segments a month, the automatic Growth rate is almost certainly the pragmatic answer.
We covered the entry point of this same crossover — when it's first worth talking to sales at all — in At What Monthly Volume Does It Make Sense to Talk to Sales?. This post is the layer above that.
What actually moves a custom quote
A deal desk isn't discounting because you asked nicely. Custom pricing gets better when the account is cheaper and more predictable for us to serve. The levers that genuinely matter:
- Consistency, not peak. 400,000 segments every month is worth more than 900,000 one month and 40,000 the next. Predictable volume is what a negotiated rate is priced against. If your sends are seasonal and spiky, the automatic Growth rate is actually a better deal for you — it flexes down in slow months with zero commitment, while a custom rate usually assumes a floor.
- Commitment / term. A 12-month commitment at a stated monthly minimum gives the desk something to price. Month-to-month at variable volume gives it much less.
- Use-case cleanliness. Registered 10DLC traffic, clean opt-in, low carrier-filtering and complaint rates. High-complaint or borderline-use-case traffic is a cost and a risk, and it works against you in a negotiation — the opposite of what people expect.
- Prepay size. Ready bills as prepaid credits via Stripe. A larger prepay commitment is a real lever on custom terms.
- Product surface. If you're also running the Power Dialer across a team, or scrubbing large lists, you're a bigger, stickier account, which changes the conversation. (Add-on pricing lives on the product and pricing page.)
If you can't check most of that list — if you're spiky, month-to-month, and only occasionally above 50K — the automatic Growth rate is doing exactly what you'd want a custom rate to do, without the paperwork.
When staying on Growth is the correct answer
Concrete cases where I'd tell someone not to bother:
- You're between 50K and ~200K/mo and the volume bounces around. The discounted pool is too small and too variable. The blended rate already floats toward $0.016 in your heavy months and rises in light ones — which is the right behavior. A committed floor would just expose you in slow months.
- Your growth is real but new. If you crossed 50K three months ago and the trend is up-and-to-the-right, negotiate later, from a higher, proven baseline. You'll get a better quote at 500K with six months of history than at 150K with a hope.
- Your margin problem is somewhere else. For agencies, the money you're leaving on the table is usually in how you rebill, not in your cost basis. Fixing an untracked carrier pass-through or a too-thin markup often beats a rate negotiation — see You Rebill Clients at $0.03 and Think You Keep $0.01.
When it's genuinely worth the call
The profile that should reach out:
- Sustained volume in the high hundreds of thousands of segments a month, ideally with a few months of history to point at.
- Willingness to commit to a term and/or a monthly floor.
- Clean, registered, low-complaint traffic.
- A prepay budget you can commit meaningfully.
If that's you, the value is no longer rounding error — a few tenths of a cent across a large, predictable pool is real annual money, and it's worth structuring properly. In that case, the honest move is to bring your actual last-six-months send data to the conversation. A quote built on real numbers beats a quote built on your best month.
The decision in one pass
Run this in order:
- Am I consistently past ~200–300K segments/mo? No → stay on Growth. Yes → continue.
- Is that volume predictable, or spiky? Spiky → stay on Growth; the automatic tier is protecting you. Predictable → continue.
- Can I commit to a term or floor and a meaningful prepay? No → stay on Growth for now, revisit with more history. Yes → continue.
- Is my traffic clean and registered? No → fix that first; it's costing you deliverability and negotiating leverage. Yes → talk to the deal desk with your data in hand.
Most senders never get past step 1 or 2, and that's not a failure — it means the automatic Growth rate is already the efficient outcome for their pattern.
The practical takeaway
The Growth drop is the part that's automatic and requires nothing from you; a custom rate is the part you earn by being large, predictable, and committed. Below a few hundred thousand consistent segments a month, the negotiation isn't worth the tenths of a cent it would return. Above it, with real history and a willingness to commit, it becomes worth structuring — and the strongest thing you can bring is your own send data.
If you want to sanity-check where you fall, pull your last six months of monthly segment volume and run it through the blended math above. If the discounted pool is small or bouncy, you already have your answer. If it's large and steady, you know who to email — and you'll walk in with the one thing that actually moves a quote.
