Failing to Provide a Clear and Easy Opt-Out Mechanism
Posted: Wed May 28, 2025 5:48 am
Failing to provide a clear, easy, and immediate opt-out mechanism is not just a mistake, but often a legal requirement and a surefire way to frustrate your audience. Every commercial SMS message must include instructions on how to opt out (e.g., "Reply STOP to unsubscribe"). Hiding this option, making it overly complicated, or delaying the opt-out process creates a negative user experience and can lead to spam complaints, which severely damage your sender reputation and lead to blacklisting. Respecting a user's decision to opt out demonstrates professionalism and helps maintain a clean database of genuinely engaged subscribers, improving overall deliverability.
Relying on Unverified or Purchased Number Lists
One of the most dangerous and damaging mistakes in bulk number marketing is relying on unverified or purchased third-party number lists. These lists are often outdated, contain invalid or recycled numbers, and most critically, lack proper consent from the individuals. Sending messages to such lists will inevitably result whatsapp data in high bounce rates, numerous spam complaints, and rapid blacklisting by mobile network operators (MNOs). This severely impacts your sender reputation, making it difficult to reach even your legitimate subscribers. Always focus on building your database organically through explicit opt-in methods, ensuring that every number on your list belongs to someone who genuinely wants to receive your communications.
Ignoring Sender ID Reputation and Registration
In Bangladesh and globally, your sender ID (the name or number that appears as the sender of an SMS) carries significant weight. A major mistake is ignoring sender ID reputation or failing to properly register your alphanumeric sender ID. Generic long codes or unfamiliar numbers are often seen as spam and are less likely to be opened. Many MNOs and regulators in Bangladesh are implementing stricter rules requiring businesses to register their alphanumeric sender IDs to combat fraud and enhance transparency. Failure to do so can lead to messages being blocked or filtered. Investing in a recognizable, registered alphanumeric sender ID builds trust, increases open rates, and ensures deliverability for your bulk campaigns.
