Let’s take a look at these steps in detail:

1. Choose a bulk SMS service provider

The first step in bulk SMS marketing is selecting the right service provider. The success of your SMS campaign also depends on the service provider you choose, so compare their features and pricing to make the right choice.

You can consider factors like user-friendly interfaces and good customer support. Also, check if they offer features like scheduling, two-way messaging, automation, and analytics measurement. Some popular options include Omnisend, Twilio, SimpleTexting, Textedly, and others. 

For example, with Omnisend, you can create SMS workflows to send messages to customers at predetermined times or triggered by specific actions:

2. Create an account and build your contact list

Before sending bulk SMS messages, build a list of contacts with your potential and existing customers.

Multiple ways to build a contact list include collecting phone numbers at checkout, offering an SMS signup option on your website or landing pages, or using popup forms to capture visitor information. Ensure you get explicit consent from customers before adding them to your list.

Once you’ve collected phone numbers, you can segment the list based on different criteria. This will help you send targeted messages that are relevant to each group. 

On Omnisend, you can either send SMS campaigns to all subscribers or create specific segments to target your audience more effectively:

3. Craft your SMS message

Now that you’ve built a contact list with all the numbers consented to receive your SMS, it’s time to craft your message.

Remember that text messages have character limits, so clarity is key. Prioritize the most relevant information. 

With the Omnisend SMS campaign editor, you can see the message limit, preview the message, add images and GIFs, and personalize the sender’s name. You can also include important opt-out instructions, which are a legal requirement in many regions.

4. Set up your bulk SMS campaign

Start by uploading your contact list to the bulk SMS service provider’s dashboard. Most platforms allow you to import contacts from CSV files easily. 

Next, select the message you crafted and/or use text message templates for inspiration.

Choose the timing for sending your messages. You can send the messages immediately or schedule them for later, depending on when your audience is most likely to engage with them. Then, review all details carefully before sending.

5. Send and analyze your campaign

You’re now all set to launch your bulk SMS campaign. After sending the messages, consider monitoring and analyzing the results to see how your campaign performs. 

Omnisend offers detailed analytics, including metrics like SMS volume, click rates, unsubscribe rates, and more. These insights help you identify what worked well and what needs improvement for your next campaign:

Let’s see how these top brands are making the most of Omnisend’s features:

Vape Superstore — SMS fuels a 77% increase in signup rates

With email marketing alone, Vape Superstore struggled to reach and engage its audience at the right time. Thankfully, SMS helped fill the gaps.

“We know that every customer that shops with us is at a different stage of their journey. Whether someone’s just quit smoking or they’ve been vaping for years, we’re here to guide and support them,” says Dan Judd, Head of Digital.

Vape Superstore started using Omnisend’s bulk SMS to promote personalized products and promotions to its mobile-user audience segment. As a result, the company saw a 77% increase in signup rates and a whopping 80% increase in mobile website traffic.

“Our customers have received the SMS really well. They appreciate the directness and the immediacy of SMS. Anyone who’s got concerns with SMS, at least try it out,” Dan recommends. “I think you’ll be surprised by the results.”

Key takeaway

SMS delivers short, targeted messages at opportune moments, helping engage subscribers who would otherwise miss or ignore emails.

Rachel Riley — Omnichannel approach delivers royal results 

Luxury childrenswear brand Rachel Riley needed to balance its traditional appeal with contemporary marketing approaches. After years with limited tools, the brand embraced a comprehensive strategy including SMS and push notifications.

“Adding these channels has allowed us to meet customers where they are, enhancing the overall shopping experience,” explains Jacqueline Love, Ecommerce Manager at Rachel Riley.

Its expanded strategy included picture messaging SMS campaigns for the US market and push notifications to capture attention in the UK. This omnichannel approach contributed significantly to its 77% Black Friday Cyber Monday revenue increase year-over-year.

Rachel Riley’s expansion from a single-day to a month-long BFCM promotion also proved successful. During this period, 48% of revenue came from Omnisend-powered communications.

Key takeaway 

Integrating SMS into a broader marketing mix creates multiple touchpoints that reinforce your message across platforms, significantly amplifying seasonal promotion results.

Vagari Bags — SMS marketing strategy yields a 121x return  

Premium men’s bag brand Vagari transformed its customer relationships by moving beyond email-only marketing to incorporate targeted SMS campaigns. Founder Jake Hughes knew his audience was missing key messages in crowded inboxes.

“Everyone has their phone on them. It’s direct, it gets opened, and it drives action,” explains Jake, who reserves text messaging primarily for product launches and exclusive offers.

The numbers validate his approach — SMS campaigns consistently achieve 6-7% click rates while delivering an extraordinary £121 return for every pound invested. Jake maintains a disciplined messaging strategy across all channels, “If I don’t have a story to tell or something interesting to share, I don’t send an email. Less is more.”

Key takeaway

SMS creates predictable revenue opportunities when used strategically for high-value moments, complementing rather than replacing storytelling in other channels.

How to write a bulk SMS message?

Effective mass texts connect with recipients as if written just for them. They read like personal messages from a trusted business to a single customer. 

Follow these seven tips to craft messages that convert.

Be concise

Your texts should be under 160 characters or 70 characters if using the Unicode charset (character set) to prevent them from splitting into two separate messages. Use Omnisend’s SMS length and pricing checker to test your content before sending it.

Personalize your message

Some mass texting services let you insert customer details like location and purchase history. Omnisend uses liquid syntax (e.g., [[contact.first_name]]) to turn bulk messages into conversations that connect with recipients.

Include a clear CTA

Every SMS needs an action for your audience to take. Make the next step obvious and accessible for recipients. Use direct action verbs like “Click,” “Shop,” or “Reply” to guide customer response and improve click-through rates.

Proofread before sending

Use a spell-checking tool like Grammarly to catch typos and grammatical problems before hitting send. Don’t be afraid to ask a colleague to review your text to spot missed issues and confirm your message communicates as intended.

Send at optimal times

Send mass texts during business hours (9 AM to 5 PM) when customers check their phones frequently. Avoid early mornings and late evenings (beyond 8 PM) when messages might annoy recipients or go unnoticed.

Respect frequency limits

Send messages only when you have valuable information to share. Bombarding customers with texts leads to opt-outs and complaints. Establish consistent timing that meets customer expectations without overwhelming them.

Track performance metrics

Measure your bulk SMS delivery rates, opt-outs, click-throughs, and conversions for every campaign. Use those metrics to refine message content, timing, and targeting. Use custom links to track subscribers outside their SMS app.

How to send mass texts legally

You can send mass texts legally by following privacy laws. In the US, the relevant law is the Telephone Consumer Protection Act of 1991 (TCPA), and in the EU and UK, it’s the General Data Protection Regulation (GDPR).

When sending text messages across international borders, you must follow your local laws and the laws of the recipient’s country. For example, if you’re texting from the UK to customers in the US, you must comply with UK regulations and US rules.

TCPA requirements

• Get explicit written permission before sending automated marketing texts to anyone
• Each company needs separate consent — no bundling multiple businesses together
• Make your consent process crystal clear that people can refuse without losing anything
• Only send messages related to what people signed up for — no bait-and-switch tactics
• Respect the Do-Not-Call Registry — it covers texts, too, not just calls
• Watch out when buying leads — you’re responsible for proving consent, not your lead provider
• Always include easy opt-out instructions in your messages
• Honor unsubscribe requests immediately — continuing to text after that is illegal

GDPR requirements

• Get explicit consent before texting customers with a clear explanation of how you’ll use their information
• Keep detailed records of when and how subscribers gave you permission
• Use double opt-in for Germany, Austria, and Switzerland, where it’s best practice
• Only send messages between 9 AM to 8 PM in your recipient’s local timezone
• Identify your brand at the beginning of every message
• Include simple opt-out instructions in all messages
• Support universal keywords like STOP and HELP in local languages
• Never bundle SMS consent with other marketing permissions
• Avoid content related to alcohol, tobacco, gambling, and adult themes

How to avoid spam reports

Even if you comply with relevant privacy and spam regulations, dissatisfied and frustrated subscribers may block and report your messages.

Follow these best practices to avoid spam lists:

• Have a point for every message, like exclusive discounts or early access
• Keep your content concise (under 160 characters) to prevent split texts
• Lead with your brand name so recipients instantly recognize who’s messaging them
• Place opt-out instructions at the end to provide an alternative to block and report
• Send texts during business hours when customers are receptive to receiving them
