A $100/mo wall between you and a runaway drip sequence.
Drip sequences and bulk blasts are powerful — and one mis-configured trigger can fire 5,000 sends in an afternoon. The Messaging Spend Cap is the per-shop ceiling that stops that from happening. Every send across SMS, email, drips, blasts, and transactional comms counts against a single monthly bucket. Default cap is $100/mo per shop. Hit it, sends pause and the owner gets a heads-up; raise it in Settings if you're running high-volume campaigns intentionally. For shops sending genuinely high volume (bulk-blast power users, multi-shop chains), BYOC mode lets you bring your own Twilio + Resend credentials and skip the cap entirely — pay your carrier directly at wholesale rates.

What's included
The full capability list.
Everything that ships on day one. No feature-gating surprises inside a single plan.
- $100/mo per-shop default cap — covers SMS segments + emails + drips + blasts
- Live spend bar visible from Settings → Messaging and from every drip/blast composer
- Owner alert at 80% / 100% — Slack-style toast + email digest
- Auto-pause on cap hit — transactional comms still flow, marketing sends queue
- Per-shop override — raise the cap in one click if you know what you're doing
- BYOC escape hatch — bring your own Twilio + Resend, skip the cap, pay carriers direct
- Audit log entry every time the cap is raised, lowered, or hit
- HQ rollup — see every shop's cap utilization across the chain on one page
Who it's for
Built specifically for…
- Every shop running drips or bulk blasts (default-on insurance)
- Multi-location owners who can't personally audit each shop's messaging config weekly
- High-volume shops who want to opt into BYOC and skip the cap entirely
What it replaces
The old way…
- The 4am Twilio bill that shows $480 because someone enrolled the entire customer base in a 7-step drip
- Manual nightly spend audits the owner kept forgetting to do
- 'I'll just turn off the campaign if it gets too expensive' — too late, you already paid
How it works
Set it up once. Run it forever.
- 1
1. Default cap is on
Every new shop ships with a $100/mo messaging cap pre-set. Counts SMS, email, drips, blasts — every send routed through SalesThumb's managed carriers tallies against the bucket.
- 2
2. Alerts fire before the wall
Owner gets a Slack-style toast + email at 80% utilization and again at 100%. Plenty of warning to either pause a sequence or raise the cap intentionally.
- 3
3. Cap hits, marketing pauses
Transactional comms (booking confirmations, payment receipts) keep flowing — the cap only pauses marketing sends (drips + blasts). Resume by raising the cap, or wait for the calendar month to roll over.
How a shop actually uses this
A new tech at Sample Shop LLC accidentally wired a welcome drip to fire on EVERY customer record (not just new ones). The trigger queued 4,200 SMS sends Tuesday at 11am. At $0.0075/segment that would've been a $31.50 hit instantly — except the shop's running spend was already at $94 from the month. Cap stopped the queue at send 800. Mike got the 100% alert on his phone at 11:04am. He paused the drip from his phone, fixed the trigger, raised the cap to $200 for the rest of the month. Saved roughly $200 in unintended sends and one very confused customer base.
Questions
Good to know.
- Does the cap block transactional comms too?
- No. Booking confirmations, payment receipts, status-change SMS, and other transactional sends bypass the cap and always go through. Only marketing-classified sends (drips + bulk blasts + scheduled campaigns) pause when the cap hits.
- Can I raise or lower the cap?
- Yes — Settings → Messaging. Every change is audit-logged so you can see who raised it, when, and to what. HQ owners can set chain-wide cap policies that individual shops can't override below.
- What's BYOC and how does it skip the cap?
- Bring-Your-Own-Carrier. Plug in your own Twilio + Resend credentials in Settings → Integrations and SalesThumb routes your shop's sends through your account at your carrier's wholesale rates. SalesThumb's cap doesn't apply because we're not the one billing you — pair with high-volume blast and drip use if you've outgrown the default ceiling.
- What if I have multiple shops?
- Each shop has its own cap. HQ rollup at /app/hq/[orgId]/messaging shows every shop's utilization on one page — useful for spotting a single shop that's about to hit its ceiling before it happens.

Software fee only — sends draw from your shop's existing SMS + email quota, capped at $100/mo by default so a runaway sequence can't bankrupt you.
Bulk blast
Built-in segments (VIPs, new in 30 days, dormant 90+, last-service-was-X), full recipient preview before send, per-blast reply-rate + revenue-attribution analytics. No third-party email tool, no Mailchimp double-billing.
Two-way SMS
Every customer conversation in one inbox. Auto-reminders run 24/7, but when they reply, a human sees it. MMS, templates, merge fields.
Automations
Build rules like 'when a quote is approved, send a deposit SMS and add a calendar hold.' Everything that happens repeatedly should be automated — and nothing should slip through.
