Bulk SMS open rates compared to email open rates

Understanding open rates in digital communication

When choosing between communication channels, open rates are a pivotal metric. The open rate reveals what percentage of your audience actually sees your marketing message. For modern businesses in Europe, the battle between bulk SMS and email is ongoing. The numbers, however, paint a clear picture: SMS leads in visibility and immediacy.

Bulk SMS open rates vs. email open rates: the facts

• Bulk SMS messages have an average open rate of 98%.
• Email marketing open rates usually range globally between 15% and 25%, depending on the industry and mailing list quality.

This stark contrast is no accident. SMS messages are delivered directly to mobile phones, triggering an instant notification. In contrast, emails often land in crowded inboxes or, worse, spam folders.

Why do SMS messages get opened more?

Several factors explain the impressive open rates for SMS:

• Immediacy: Most people carry their mobile phones everywhere, ensuring rapid delivery and prompt attention to SMS.
• No spam filters: SMS inboxes are less cluttered and have minimal filtering, increasing the chance your message is seen.
• Short and direct: People associate SMS messages with concise and relevant information, making recipients less likely to ignore them.
• User behavior: On average, recipients open SMS messages within 3 minutes of receipt.

Email open rates: challenges and opportunities

Despite the lower average open rates, email still plays a significant role in digital marketing. However, several challenges hamper its effectiveness:

• Inbox overload: Users receive dozens (if not hundreds) of emails daily.
• Spam and promotions tabs: Many marketing emails never reach the primary inbox.
• Longer messages: Emails often require more time and attention to read, leading to lower immediate engagement.

Email works best for longer-form content, detailed updates, or when attachments are necessary.

When to choose bulk SMS over email

Bulk SMS should be considered when goals include:

• Reaching customers with time-sensitive information (flash sales, reminders, OTP sms, service updates)
• Maximizing engagement for announcements and personalized offers
• Automated birthday greetings or appointment reminders
