Quick Answer

Agency SMS marketing means running bulk SMS, WhatsApp and RCS campaigns on behalf of brand clients, from planning and DLT templates to delivery and reporting. SMSGatewayHub gives agencies a DLT-compliant platform with promotional routes, short code and long code lead capture, scheduling, campaign reports via API or panel, and a white-label reseller option, all on Pay As You Go pricing.

Why should agencies add SMS to the channel mix?

Clients judge agencies on returns. SMS is one of the few channels that reaches almost every mobile phone in India and is typically read within minutes, which makes it a strong complement to social, search and print. SMSGatewayHub lets agencies create and send attractive SMS campaigns with links to images, files, discount vouchers and personalised offers, and even track the effectiveness of offline and online advertising campaigns.

Agencies use the same platform for several jobs: promotional SMS for client offers, RCS rich cards and the WhatsApp Business API for visual campaigns, and transactional SMS for client-side alerts such as lead notifications and payment receipts.

Better bang for your buck

Promote special offers

Enhance client campaigns with special offers and discount vouchers, from voucher creation to redemption.

Leads from offline ads

Put a call-to-action on billboards, print and radio: readers text a keyword to your client's short code or long code for an offer, and every lead is captured.

Track SMS campaign metrics

Generate detailed campaign performance reports via API or download them from the panel to share with clients.

Quicker way to reach clients

Share a media plan, ad copy or proposal link by SMS instead of waiting for clients to open email.

SMS alerts

Send automated reminders, meeting updates, campaign alerts and payment receipts to clients by integrating your CRM with our SMS gateway APIs.

SMS scheduling

Log in once and schedule messages to be delivered at the exact date and time you choose.

Offline-to-online lead capture workflow

Turning a billboard or newspaper ad into measurable leads

  1. Choose a keyword

    Reserve a campaign keyword on a short code or a dedicated long code for the client.

  2. Publish the call-to-action

    Print "SMS OFFER to the number" on billboards, flyers, radio scripts and in-store standees. A missed call number works too.

  3. Auto-reply instantly

    Each inbound message triggers an auto-reply with the offer code or landing page link.

  4. Push leads to CRM

    Inbound numbers are forwarded to the client's CRM or sheet by URL for sales follow-up.

  5. Report by medium

    Use a different keyword per medium or city to compare which placement produced leads.

DLT compliance checklist for agency campaigns

Under TRAI DLT, the brand (principal entity) owns headers and templates; the agency operates on its behalf.

ItemWho registersWhat agencies should know
Principal entityClient brandEach client must be registered on a DLT portal with its own entity ID.
Headers (sender IDs)Client brandPromotional campaigns use numeric headers; service messages use 6-character alphanumeric headers.
Content templatesClient brand, often prepared by the agencyVariables must be tagged; URLs and phone numbers must be whitelisted.
Telemarketer chain bindingClient binds the chain on DLTThe PE-TM chain must include the delivery partner for messages to pass scrubbing.
TimingAgencyPromotional SMS goes out only within TRAI's permitted hours and not to DND-blocked categories.

See our guides to DLT registration and PE-TM chain binding.

Manage many clients from one account

Agencies typically create a sub-user per client, each with its own credits, sender IDs and templates, and lock templates so no one sends unapproved content. Reports can be pulled per sub-user for monthly client reviews. When a client needs a voice campaign, voice SMS is available on the same platform.

Many agency clients are retailers and event organisers, so see our retail and event management case studies for campaign ideas, and read bulk SMS campaign best practices.
