Bulk SMS vs Email Marketing in Tanzania: Which Works Better?

Use SMS for short reminders and alerts that must work without mobile data, and email for detailed information, attachments and newsletters. Neither channel is always better. Choose according to customer preferences, the action required and the cost per useful outcome, then test with your own audience.

Reach and open rates

SMS works on compatible feature phones and smartphones without a data bundle, although coverage, handset availability and network filtering affect delivery. Email needs an internet connection when the recipient checks their inbox. Neither a delivered SMS nor an email open metric proves that a person read the content or acted on it.

Cost

Compare total campaign cost rather than assuming email is free. Email tools may charge by contacts or volume; SMS uses credits per recipient and segment. Include content preparation, discounts and follow-up work when comparing cost per booking or sale.

When to use each

• Use SMS for appointment reminders, payment and delivery alerts, OTPs, and flash promotions.
• Use email for detailed newsletters, receipts, and content that benefits from images and links.
• Combine them: send an email campaign, then a short SMS nudge to lift response.

For example, send a detailed event programme by email, then a short SMS reminder to recipients who agreed to that channel. Do not send an extra nudge just because an email tracking pixel did not record an open. Keep each message useful and respect customer preferences.

A fair comparison for your next campaign

• Choose one measurable goal, such as confirmed bookings, rather than comparing unrelated open-rate claims.
• Use comparable audience groups and the same offer period. Keep a holdout group if practical.
• Track unique codes or booking links and compare gross profit after campaign costs.
• Record consent separately for each marketing channel and provide a working opt-out.
