SMS vs Email: What You Need to Know When Messaging Patrons

SMS vs Email: What You Need to Know When Messaging Patrons

A guide on how to choose the right communication for your message

When your library is choosing what type of message to send to your patrons, there are a few considerations to keep in mind. Many MessageBee users have both email and SMS subscriptions, so they have options on what channels to use when messaging but picking the best one and pairing that with the right messaging will ensure smooth deliverability, and that patrons will act on their message.

 

First, we need to discern the different types of messages that MessageBee can send. There are two different categories of communications, Transactional and Marketing. Each kind of message has a specific purpose and use. Transactional messages are used to update patrons on their borrowing activity, while marketing messages are for keeping patrons current on everything else, like newsletters and events. Check out this graphic to help guide you:

MessageBee allows libraries to communicate with patrons through both email and SMS, but each channel serves a different purpose. Email messaging is ideal for messages that contain more detail, because they can include rich content like images, links, and other multimedia content.

 

SMS notifications, on the other hand, are perfect for quick, time-sensitive alerts like due date reminders, holds ready, or library closures, as they are seen immediately on patrons’ phones. Understanding the strengths of each channel helps libraries ensure their messages reach patrons effectively while maintaining clarity and engagement.

Principles for Messaging

Keep your content relevant and engaging with readers

Writing and sharing content that your readers are interested in is the most important thing with newsletters. The more people that open and read your emails, the better.

Make it readable at-a-glance

Did you know that 74% of readers only glance at newsletters? Make your emails quickly scannable with clear headlines, sections, and plenty of images. Including things like bulleted and numbered lists will translate into more eyeballs on your emails.

Send often, but not too often

According to Campaign Monitor, best practice for sending newsletters is at least once a month, but no more than twice a week.

Pros & Cons of Email vs SMS Messaging

Each communication channel brings unique strengths — and limits. Use this quick matrix to choose the right tool for the right message.

SMS

Pro

Lots of information in each communication

Emails can include images, links, videos, and more. Lead with the most important details and use a strong subject line.

Pro

Seen immediately by subscribers

SMS messages are opened quickly and work best for reminders, due dates, and urgent notices happening soon.

Con

Readers must open the message

Inbox overload means many patrons may ignore or delay reading emails.

Con

Limited information per message

SMS is limited to about 160 characters and text-only. Too many links can hurt deliverability and increase costs.

FAQs for Messaging Patrons

Here are some common questions to guide you through selecting the correct communication.

What is the difference between transactional and marketing messages?
MessageBee supports two kinds of library communication: routine updates tied to borrowing activity and outreach that promotes programs and services — all with modern, branded designs that are easier for patrons to read and act on.

Transactional messages: automatic notices about holds, due dates, reminders, and other account activity (via email or SMS).
Marketing messages: targeted outreach such as newsletters, event announcements, and community updates to engage patrons and promote the library.
What is the content of the message you want to send?
Before sending any marketing message, start by creating a list. Because MessageBee connects to your ILS, you can easily build accurate lists — from “all patrons” to highly targeted groups based on age, branch, or other criteria.

For broad updates like newsletters, send to everyone. For more specific topics, use dynamic lists to reach only the patrons who need it. (See our deliverability guide for details on list types and setup.)
When should I send an SMS instead of an email?
Use SMS for short, time-sensitive updates that patrons need to see quickly — things like holds ready for pickup, last-minute closings, or reminders due today or tomorrow.
When is email the better option?
Use email for anything that needs more context, images, links, or explanation — newsletters, program highlights, policy updates, multi-step instructions, or anything patrons may want to reference later.
How long should SMS messages be?
Keep texts brief and actionable (under 160 characters). Include only what patrons need to know.
What messages should not be sent by SMS?
Avoid long explanations, sensitive topics, or items requiring attachments or graphics. Those belong in email.
What’s best for emergency or unexpected closures?
Send SMS first for speed, then follow that with an email that provides additional information such as hours, locations, and next steps.
Are transactional notices handled differently than marketing messaging?
Transactional notices (due dates, holds, reminders) are typically automated and can use SMS or email depending on patron preferences. Marketing and outreach messages (events, newsletters, campaigns) are better suited for email — with SMS used sparingly for high-impact promotions or reminders.
How do SMS limits affect what I send?
Because SMS has character limits, it’s best used for short alerts. If you need paragraphs, attachments, or multiple links, use email.
What about accessibility and ease of reading?
SMS is excellent for quick alerts on mobile devices. Email offers better formatting options, larger text, images, and screen-reader support for longer content.
