Building a clean subscriber list.

A. Importance of having a clean list.

A clean subscriber list is the cornerstone of a successful SMS marketing campaign. It's not just about having a long list of contacts; it's about updating the list to reflect your engaged and interested subscribers. 

Here's why a clean list matters:

1. ‍Higher engagement: When your list consists of people who genuinely want to receive your messages, you're more likely to see higher engagement rates, which can translate into increased sales, traffic, or other desired actions.
2. ‍Compliance: Maintaining a clean list ensures compliance with SMS marketing regulations. Sending messages to recipients who haven't opted in can lead to legal issues and damage your brand's reputation.‍
3. Cost-efficiency: SMS marketing often involves costs per message. Sending messages to uninterested recipients not only wastes money but can also result in higher unsubscribe rates, which could impact your overall campaign effectiveness.‍
4. Better data insights: A clean list provides more accurate data for analysis. You can better understand your audience, their preferences, and behaviors when your list is free from irrelevant or uninterested contacts.

B. Methods to collect opt-ins.

Building a clean list starts with obtaining permission from your recipients. Opt-ins are a crucial part of this process, and there are several effective methods to collect them:

1. ‍Keyword-based opt-ins: Encourage people to text a specific keyword to a designated number to subscribe. For example, "Text 'DEALS' to 12345 to receive exclusive offers."
2. Web forms: Use web forms on your website or landing pages to capture opt-ins. Ensure clarity about what subscribers can expect to receive.
3. Point of sale: If you have a physical store, ask customers for their permission to send SMS updates when making a purchase.
4. Contests and giveaways: Running contests or giveaways can be an effective way to collect opt-ins. Just make sure that people understand they're subscribing in the process.
5. Social media: Promote your SMS campaign on social media platforms and provide a clear opt-in method.

C. Managing unsubscribers.

Managing unsubscribers is as important as collecting opt-ins. It ensures that you respect your subscribers' preferences and maintain a positive brand image. Here's how to handle unsubscribers effectively:

1. Opt-out process: Make the opt-out process easy and straightforward. Include clear instructions in every message, such as "Text 'STOP' to unsubscribe."
2. Prompt removal: As soon as someone opts out, promptly remove them from your SMS list. Continuing to send messages to unsubscribed individuals can lead to complaints and legal issues.
3. Feedback gathering: If possible, ask unsubscribers for feedback about why they chose to unsubscribe. Use this information to improve your SMS marketing strategy.
4. Respect privacy: Ensure that unsubscribers' information is not shared or used for any purpose other than unsubscribing them from your SMS list.

When you focus on having a clean list, you'll become better equipped to build and maintain a healthy and engaged subscriber list for your SMS marketing campaigns.

SMS campaign restrictions in Nigeria.

When it comes to SMS campaigns in Nigeria, there are specific rules and exceptions, particularly for Promotional Routes. Here's what you need to know:

1. Do not disturb (DND) list: Messages sent to numbers on the DND list will not be delivered.
2. International references: Avoid mentioning international organizations like WhatsApp and Facebook on this route, as they are considered international SMS and may get blocked by the network operator's firewall.
3. Numeric senderIDs: Messages with senderIDs containing numeric characters cannot be delivered. Ensure your SenderIDs do not include any digits for successful delivery.
4. Prohibited keywords: Certain keywords such as "win," "promo," "free," "Giveaway," and "Congratulations!!!" are not allowed. Additionally, political content, as per network operator notifications, may be prohibited. Operators hold the discretion to block content or SenderIDs at their discretion.
5. SenderID account distinction: SenderIDs used for transactional accounts cannot be used to send promotional messages. They should both have specific sender IDs for each route.
6. Time restrictions: Messages sent between 8 p.m. and 8 a.m. on the promotional route won't be delivered due to NCC restrictions. They will be queued and sent out after 8 a.m the following day to ensure compliance while respecting permissible hours.
7. Airtel senderIDs: For Airtel, senderIDs must be registered in advance to ensure proper delivery. Messages to Airtel subscribers with unregistered SenderIDs may be sent with a default SenderID. Network operators have the authority to block specific content, and continuous inappropriate content may result in the blocking of the SenderID itself.
8. Special characters: While special characters like emojis, symbols, and non-standard characters can add personality to your messages, they may be subject to extra charges and are identified as anything outside of letters (A-Z, uppercase, and lowercase), numbers (0-9), full stop, and comma punctuations, depending on the network provider. Be aware of potential cost variations for using special characters.

2. Response rates: Measure the response rates to assess campaign effectiveness. Analyze which messages and strategies yield the best responses and tailor your future campaigns accordingly.
3. Feedback and metrics: Gather feedback from recipients when possible, and use analytics tools to track metrics like open rates and click-through rates. These insights can guide your campaign refinements.
4. A/B testing: Conduct A/B testing to compare different elements of your campaigns, such as message content, timing, and sender names. This iterative process helps fine-tune your SMS marketing strategy.
