10DLC campaign warm-up schedule: how to ramp SMS volume on a new aged insurance lead list

Registration isn't the same as throughput

10DLC registration gets your brand and campaign approved so carriers will carry your traffic at all — the registration guide covers that part. Approval is a yes/no gate. Throughput is a separate, ongoing number: the messages-per-second and per-day cap a carrier actually lets through for your campaign, and it starts low regardless of how clean your brand vetting score is. A new campaign that passes registration on Monday and gets pointed at a 20,000-lead file on Tuesday doesn't send 20,000 texts — it sends however many clear the day's cap, and the rest queue, delay, or get filtered depending on the aggregator.

Why carriers ramp new campaigns instead of trusting the vetting score

Vetting score sets your ceiling. It doesn't set your starting point. Carriers watch a new campaign's early sending behavior — delivery rate, complaint rate, how many recipients reply STOP, how many numbers bounce as disconnected or invalid — before they raise the cap toward what the vetting score allows. A campaign that opens at full volume and immediately produces a spike of undeliverable sends or opt-outs reads the same to a carrier's filtering system whether the sender is a spammer or an insurance agent texting a legitimate aged list for the first time. The ramp exists so a new campaign can prove it's clean before it's trusted with volume.

A four-week ramp that works on a typical aged batch

Exact caps vary by aggregator and registered use case, so treat the day counts below as a shape to follow, not a number to hit precisely — your aggregator's dashboard shows your actual daily allotment, and that number is the one to respect.

• Days 1–3 — low and watched. Send a small, fixed batch each day, well under whatever cap your aggregator shows. Don't split by state or age band yet — just confirm the basics: delivery receipts coming back clean, no mass carrier rejections, no early STOP spike. This is the slice of the list you can afford to burn if something's misconfigured.
• Days 4–10 — step up every two to three days. If delivery and complaint signals stayed clean, raise the daily send in modest steps rather than one jump — doubling every two to three days is a common, conservative pace. Watch the same metrics after every step up, not just once at the end of the week.
• Days 11–21 — scale toward your allotted cap. By this point a clean campaign is usually earning a materially higher cap from the aggregator on its own, on top of whatever you've ramped manually. Keep stepping up until your daily send matches what the dashboard shows you're cleared for.
• Day 21+ — steady state, re-check after any pause. Once you're at full allotted throughput, stay there — but if the campaign goes quiet for a week or more (between batches, during a slow month), step back down and ramp again rather than resuming at full volume cold. Carriers read a sudden resumption the same way they read a sudden start.

Stage the list, don't dump it

The ramp only works if the list behind it is staged to match. If you just bought a large aged batch, split it into daily sending blocks sized to each week's cap before you load anything into the dialer or texting platform — the same way splitting a list into daily calling batches turns one CSV into a week's worth of work instead of a single pile. State or age-band slicing can wait until week two or three, once the campaign has room to send more than the ramp's early minimum in a day. Trying to hand-pace sends against a cap you're tracking in your head is how a campaign drifts over the limit on a busy Tuesday; blocking the file out in advance removes the guesswork.

Protect the ramp with a clean file, not just a slow one

Early delivery and complaint signals are exactly what the ramp is being judged on, so a file with dead numbers or landlines mixed in does more damage in week one than it would once you're at full throughput — every undeliverable send during the watched period looks like a quality problem to the carrier, not a data problem. Run the DNC scrub and a phone-type check before day one, not after a bad week forces you to. A bundled scrubber is the practical way to do both in one pass; the one we point buyers at is Landline Remover (disclosure: that's an affiliate link, and we may earn a commission if you sign up through it) — upload the CSV and it strips landlines, disconnected numbers, and DNC-listed contacts before any of them reach a campaign you're still trying to build trust on.

What to watch instead of your gut

• Delivery receipts. Your platform should surface delivered vs. failed per batch — a rising failure rate is the first sign to pause the ramp, not push through it.
• Carrier error codes. Codes that point at filtering or spam flags mean slow down; codes that point at an invalid or disconnected number mean the file needs another scrub pass, not a slower ramp.
• STOP / opt-out rate. A spike here is a message or targeting problem, and it also feeds directly into how carriers score the campaign — the STOP-handling guide covers the keyword set and suppression workflow that needs to be live before you send message one, ramp or no ramp.
• Queued vs. sent. A growing queue means you've hit the day's real cap even if the dashboard number looks higher — stop pushing more in and let it clear.

Not legal advice

This is a practical sending guide, not legal or compliance advice. Carrier throughput tiers, vetting criteria, and aggregator rules change and vary by provider, and 10DLC sits alongside — not in place of — TCPA, state telemarketing statutes, and your own carrier agreement. Confirm your actual caps and review timelines with your registered aggregator, and talk to counsel familiar with texting compliance before you scale a multi-state campaign.

Buy the list sized to the ramp you're running

If you're about to register a new campaign, buy a batch sized to what you can actually send during the first few ramp weeks rather than the biggest file your budget allows — a smaller order that clears the ramp cleanly beats a large one that spends its first month throttled. Link Leads lists run $0.012 per lead with a 5,000-lead minimum ($60.00), SMS or email, any state or age band in the builder at link-leads.com.
