Given that a significant portion of email and virtually all SMS messages are consumed on mobile devices, failing to optimize your communications for mobile is a critical oversight. Emails that don’t render correctly on smartphones, require excessive scrolling, or have tiny text frustrate recipients and lead to immediate deletion. SMS messages, by their nature, are concise, but any linked landing pages must also be mobile-responsive. Prioritize clear, concise copy, single-column layouts, large fonts, and easily tappable calls-to-action to ensure a seamless mobile experience for your audience in Bangladesh and globally.
Ignoring Regulatory Compliance and Privacy Laws
The most severe mistake, with potentially devastating consequences, is disregarding local and international data privacy regulations. For phone number list businesses in Bangladesh, this specifically means strict adherence to the Personal Data Protection Ordinance (PDPO 2025) for all email and SMS communications. This includes explicit consent, transparent privacy policies, easy opt-out mechanisms, data breach notification procedures, and robust data security. Ignorance is not a defense, and non-compliance can result in substantial fines, legal action, and irreparable damage to your brand’s reputation and customer trust.
Lacking Clear Calls-to-Action (CTAs)
Every email and SMS sent should have a clear, concise, and compelling Call-to-Action (CTA). A common mistake is to send messages without what is digital marketing tools and why it matters guiding the recipient on what to do next, or burying the CTA within a lengthy message. CTAs should be prominent, use action-oriented language (e.g., “Shop Now,” “Learn More,” “Book Your Slot”), and provide a direct path to the desired action. Without a strong CTA, even highly engaged subscribers might not know how to proceed, leading to missed conversion opportunities.
Failing to Test Campaigns Before Sending
Sending out email and SMS campaigns sms to data without thorough testing is a recipe for disaster. This common mistake can lead to broken links, incorrect personalization, formatting errors across different devices, and even accidental non-compliance. Always test your campaigns rigorously across various email clients, mobile devices, and operating systems. Send test messages to internal team members, verify all links, and double-check personalization tokens before hitting send, ensuring a flawless execution for your entire database.
