One of the most common questions Nigerian businesses ask about SMS marketing is how often to send. Send too rarely and customers forget about you. Send too frequently and customers opt out or complain. Here is how to find the right frequency for your business.
Industry Benchmarks for Nigerian Businesses
Retail and e-commerce: 2–4 messages per month. Banking and financial services: Transactional alerts as needed, marketing 1–2 times per month. Healthcare: Appointment reminders as needed, health campaigns 1–2 times per month. Education: As needed for important updates, maximum 4 promotional messages per month. Events and entertainment: 2–4 messages per event cycle.
The Role of Value in Frequency
The optimal frequency is directly related to the value of your messages. Businesses sending high-value, highly relevant messages can send 6–8 times per month with low opt-out rates. Businesses sending generic promotions see high opt-out rates at even 2 messages per month. Improve your message value before increasing frequency.
Monitoring Opt-Out Rates
Your opt-out rate is the clearest indicator of frequency tolerance. If opt-outs spike after you increase send frequency, you have exceeded your audience's tolerance. Industry benchmark opt-out rates are below 0.5% per send. Above 1% per send signals frequency or relevance problems.
Triggered Messages vs Campaign Messages
Triggered messages (sent in response to customer actions — new signup, purchase, abandonment) have higher frequency tolerance than broadcast campaigns because they are inherently relevant to the recipient's current context. A customer who just made a purchase expects a confirmation message — they will not opt out when they receive it.
Seasonal Frequency Adjustments
During high-relevance seasons — Christmas, Eid, school resumption — Nigerian consumers are more receptive to higher message frequencies. A retailer that typically sends 2 messages per month can increase to 4–6 messages per month in November/December without significant opt-out rate increases.
