A common flaw in email and SMS campaigns is the absence of a clear and compelling call-to-action (CTA). Your message should always guide the recipient towards a specific next step. Vague or multiple CTAs can confuse the user and lead to inaction. Whether it's "Shop Now," "Learn More," "Register Here," or "Call Us Today," the CTA should be prominent, easy to understand, and provide a clear benefit. For SMS, a concise link or a specific reply keyword is essential. For emails, a prominent button or hyperlinked text works best. Failing to include a strong CTA means lost opportunities for conversion, as recipients won't know what you want them to do next.
Over-Communicating or Under-Communicating
Finding the right frequency for email and SMS communication is a delicate balance. Over-communicating can lead to subscriber fatigue, annoyance, and high unsubscribe rates, as recipients feel overwhelmed by too many messages. Conversely, under-communicating can lead to your brand being forgotten, whatsapp data with subscribers losing interest or forgetting why they opted in. The optimal frequency varies by industry, audience, and the type of content you're sending. Regularly surveying your audience, monitoring engagement metrics (open rates, click-throughs, unsubscribes), and adjusting your sending frequency based on data is crucial for maintaining subscriber interest and maximizing long-term engagement.
Failing to Optimize for Mobile Devices
Given the dominance of mobile devices in 2025 (especially in Bangladesh), a critical mistake is sending emails or SMS messages that are not optimized for mobile viewing. Emails with tiny fonts, stretched images, or unresponsive layouts will lead to frustration and immediate deletion. SMS messages that are too long or break into multiple parts can be inconvenient. Ensure your email templates are responsive, your images are optimized for mobile loading speed, and your text messages are concise and easy to read on small screens. A seamless mobile experience is paramount for engagement, as most recipients will access your communications on their smartphones.
