Why Work with an SMS Marketing Agency?

While DIY platforms are popular, agencies offer an edge when it comes to:

  • Shortcode provisioning & compliance

Working with experts can help avoid carrier restrictions, spam traps, and delivery issues, especially when scaling campaigns across multiple countries.

Choosing the Right Partner

When selecting an agency, especially for campaigns targeting Nigeria or other African nations:

  • Verify Regional Expertise: Does the agency understand local regulations, carrier networks, consumer behaviour, and compliance (e.g., NCC regulations in Nigeria)?
  • Assess Service Scope: Do you need a dedicated SMS specialist or a full-service digital agency that includes SMS? Are you looking for strategic help or primarily bulk sending capabilities?
  • Check Case Studies/References: Look for proven success within your target market or industry.
  • Consider UK Needs: If running campaigns both globally and in the UK, ensure the agency can effectively manage both.

How to Choose the Right SMS Marketing Agency

Here’s what to evaluate when selecting a provider:

  • Coverage & Reach: Do they support delivery in your target countries?
  • Compliance & Opt-out: Are they aligned with DND, GDPR, or local rules?
  • API & Dashboard: Is it easy to send messages manually or programmatically?
  • Support & SLAs: Do they offer responsive customer service?
  • Cost & Volume Discounts: Are prices scalable as you grow?
