What is Promotional & Bulk SMS Campaigns?
Dollu's promotional and bulk SMS service gives marketing, growth and CRM teams one platform to reach customers at scale - from a 5,000-contact flash sale to a 50-million-message festive campaign. Upload or sync your audience, compose the message with merge fields, choose a sender ID and send immediately or schedule for the right local hour in each market. Messages leave our platform over the same 800+ direct operator connections that carry our transactional and OTP traffic, so promotional sends travel on real routes with real delivery receipts rather than grey-route guesses.
The campaign portal is built for non-technical users without hiding the detail. Segment contacts by attributes, tags, purchase behaviour and past engagement; personalise every message with dynamic fields; A/B test copy and sender IDs on a sample before committing the full list; and set send-rate throttles so your call centre and website are not overwhelmed by the response. Short links are generated on a branded or shared domain and every click is attributed to the contact, campaign and variant, so you get conversion data rather than delivery counts alone.
Consent and compliance are enforced at the platform level, not left to each campaign owner. Contact records carry per-market consent status and source, opt-out keywords such as STOP and their local-language equivalents are honoured automatically, and suppression lists are applied on every send. In India, templates, headers and consent are checked against DLT registration before dispatch; in the US, TCPA quiet hours and 10DLC campaign registration are enforced; in the EU and UK, GDPR-aligned consent capture, data residency and retention controls apply. Reports show exactly who was contacted, when and on what basis.
Whether you run campaigns yourself through the portal, trigger them from your CRM over our REST and SMPP APIs, or ask our managed campaign desk to execute them for you, the same delivery engine, routing intelligence and analytics apply. Real-time dashboards show sent, delivered, failed, clicked and opted-out counts per campaign, per market and per operator, and results export to CSV, webhook or your data warehouse so attribution lands where your marketing team already works.
A2P SMS path: from your application to the handset.
Why choose Dollu for promotional sms.
The advantages of buying from a carrier that owns its network, interconnects and operations - rather than a reseller.
More engagement per message sent
Segmentation, local-hour scheduling and personalisation lift open and click rates, and click attribution shows which segments and variants actually convert.
Compliance you do not have to build
DLT template checks, TCPA quiet hours, GDPR consent records and universal opt-out handling are enforced by the platform, reducing regulatory exposure and manual review.
Deliverability from real routes
Promotional traffic rides the same direct operator connections as our OTP and transactional SMS, with operator-level delivery receipts and no grey-route surprises.
One list, every market
Run a single campaign across 200+ countries with per-market sender IDs, languages, quiet hours and consent rules applied automatically by destination.
Attribution, not just delivery counts
Click-level tracking, conversion webhooks and warehouse export let you tie SMS spend to revenue in the tools your marketing team already uses.

How it works.
From first conversation to live traffic - a tracked, engineer-led onboarding with a named owner at every step.
- Step 01
Onboard and register
Create your account, add brands and sender IDs. Our team completes DLT, 10DLC or local sender-ID registration where the destination requires it, typically within one to five business days.
- Step 02
Import and segment
Upload contact lists or connect your CRM. Numbers are validated and de-duplicated on import and existing opt-outs are applied automatically. Build the segments you plan to target.
- Step 03
Build, test and schedule
Compose the message with merge fields and short links, send test messages, run an A/B split on a sample and schedule the full send by local time zone.
- Step 04
Send, measure, optimise
Watch delivery, clicks and opt-outs in real time. Export results or receive them by webhook, then feed learnings into the next segment and template.
Direct, premium or grey.
Where an SMS route class shows up: in delivery, in the sender ID your customer sees, in the truthfulness of the delivery receipt and in the compliance risk you carry.
| Dimension | Direct operator | Premium aggregated | Grey routesNot offered by Dollu |
|---|---|---|---|
| Delivery | Direct SMPP bind to the mobile operator; the highest and most consistent delivery | Via a vetted hub or Tier-1 aggregator holding operator agreements; high delivery with occasional re-routing | Via SIM farms or unauthorised international paths; unpredictable, filtered and blocked without notice |
| Sender ID | Registered alphanumeric ID, short code or long number preserved exactly | Registered sender ID normally preserved; may be substituted on a few destinations | Overwritten with a random numeric sender; your brand is invisible |
| DLR quality | Handset delivery receipts from the operator | Operator or hub receipts; reliable, occasionally delayed | Fake or aggregator-generated receipts; no proof of delivery |
| Compliance risk | Lowest - operator-approved, with DLT, 10DLC or sender-ID registration completed up front | Low - operator agreements in place; Dollu vets every hub it uses | High - breaches operator terms and local law; carries fines, blacklisting and lost sender IDs |
| Price position | Highest per message; the lowest cost per delivered, verified message | Mid | Lowest headline price; the hidden cost is failed OTPs, blocked traffic and brand damage |
Dollu does not sell grey routes. Every destination on our deck is direct operator or premium aggregated, and the route class is shown against each price so you know exactly what you are buying.
