Bulk and mass texting services allow you to send SMS messages to all your contacts simultaneously — ideal for marketing, updates, and alerts. You compose a message, define its region and delivery settings, assign a contact list, and press send. It’s that simple.

High engagement rates come when you personalize texts (for instance, Omnisend supports liquid syntax such as [[contact.first_name]]). You can also segment subscribers, such as those who purchased in the last 30 days, and create targeted bulk campaigns.

How to send bulk SMS using a mass texting service (step-by-step guide)
If starting bulk SMS marketing as a beginner seems like a daunting task, here’s a step-by-step process you can follow to get started:
Watch this short video to learn how to send mass texts in 60 seconds:
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.
Image via Omnisend
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.
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:

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.
Note
This guide offers general information only, not legal advice. Rules may change. Omnisend customers should consult qualified legal professionals to ensure their messaging practices comply with current regulations in all countries where they operate.
TCPA requirements for mass texting
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 so 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 for mass texting
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

Leading brands are using Omnisend’s bulk SMS features to drive engagement, recover abandoned carts, and boost revenue.
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
Personalized bulk 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 bulk 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 bulk 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
Mass texting creates predictable revenue opportunities when used strategically for high-value moments, complementing rather than replacing storytelling in other channels.
Real-world use cases: Bulk SMS examples from Omnisend clients
Mass texting services can be adapted for different scenarios, and they’re particularly suited to the unique needs of different sectors. Let’s review the use cases of bulk SMS services in various scenarios:
Promotions & flash sales
Ecommerce businesses can use bulk SMS to drive customer engagement. They use it to announce promotions, offer discounts, and other sales.
1. Bulk SMS example from Vape Superstore
Subject line: “Big Sale — Up to 60% Off! Best deals on E-Liquids & Kits.”
2. Bulk SMS example from Rachel Riley
Subject line: “Cyber Monday: Shop 50% + Extra 25% Off.”
Why bulk SMS promotions drive results
Clear deadlines help to create urgency and FOMO, and because SMS are delivered instantly, the time-sensitive nature of the messages can result in significantly higher engagement and response times.
Product launches & restocks
3. Bulk SMS example from Vagari Bags
4. Bulk SMS example from Dona Jo
Why bulk SMS works for product launches
The immediate and concise nature of SMS makes it an ideal channel for letting your customers know about new or limited-edition launches.
Clearance & inventory updates
5. Bulk SMS example from Dona Jo
6. Bulk SMS example from Rachel Riley
Why bulk SMS works for clearance campaigns
Similar to promotions and sales, SMS is a great channel for creating FOMO — and not many things generate more FOMO than telling customers they’re at risk of missing out on a product they like. Combining a “last chance” message with the immediacy of SMS makes for a very powerful combo.
Personalization & VIP messaging
7. Bulk SMS example from Vagari Bags
8. Bulk SMS example from Nine Lives Bazaar
Why personalized bulk SMS drives engagement
Personalization helps to make a message feel more relevant to the recipient. This makes it more likely that they’ll place an order with you, which is one reason why personalization is so effective at improving response and retention rates.
Rich media & visual promos (MMS)
9. Bulk SMS example from Day Designer
10. Bulk SMS example from Rachel Riley
Why rich media enhances bulk SMS performance
Visual media, like photos and GIFs, help your messages stand out. They may inject some humor, help to make the product more tangible, or just make the message more memorable. The end result is heightened brand identity, which can lead to higher engagement and conversions.
