Mass texting service for sending engaging bulk SMS
Connect with thousands instantly using Omnisend’s powerful mass texting service. An automated bulk SMS service allows you to personalize messages and track performance in real-time — all from one platform. With Omnisend, you can:
Combine SMS, email, and push into one seamless omnichannel strategy
Launch pre-built automated workflows to save time and stay consistent
Build your SMS list with TCPA-compliant popups and landing pages
Bulk SMS is the sending of promotional and informational texts to multiple customers. Unlike automated flows that trigger individually, bulk SMS goes to predetermined segments on your schedule, typically for sales, product launches, or time-sensitive offers.
How does bulk texting work? You upload your list to a platform like Omnisend, write your message, pick segments, and schedule or send it. Your tool then distributes your text through its carrier networks, delivering within seconds.
Because bulk SMS reaches as many people as possible, it also helps test offers and create browsing sessions, which provide additional data points for segmentation and future targeting.
This article is a complete guide to mass texting, covering its one-time blast potential, role in your broader marketing strategy, actionable tips, benefits, and best practices.

What are the benefits of sending bulk SMS messages?
Send one message, reach thousands. Bulk texts let you communicate with your entire subscriber list or chosen segments via a scheduled or manual send, with no copying, pasting, or repetitive work required.
Sending mass SMS messages helps you to:
Get seen when customers look at their phones: Your text lands next to messages from friends and family, not buried under promotional emails they’ll delete tomorrow.
Interrupt the buying process at the perfect moment: Customer comparing prices during a sales event? Text them a discount code before they enter their credit card elsewhere.
Create urgency across your list: Send “two hours left” to thousands of customers at once, triggering a wave of purchases from people waiting for a reason to buy.
Jump on sudden changes and trends: A cold snap hits, and everyone needs winter gear right now. Your competitor runs out of stock. Bulk SMS messages let you capitalize while the opportunity exists.
Success story
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 concerned about 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.
How do you send bulk SMS messages to your customers?
Sending bulk texts is probably the easiest marketing activity you’ll ever do. All you need is a sending tool, a contact list, and a budget for the SMS credits:
Choose your bulk SMS platform
Omnisend handles thousands of texts in one click while syncing with Shopify, WooCommerce, BigCommerce, and Wix via native apps.
Invalid numbers get flagged before you waste money texting disconnected lines. Carrier relationships are managed behind the scenes so your messages bypass spam filters.
Import or sync your contact list
TCPA compliance isn’t optional. Every recipient needs documented opt-in consent. CSV uploads work, but direct store syncing prevents manual errors.
Remove anyone who hasn’t opened a text in 90 days. They cost you money and drag down engagement rates.
Create your message
Characters are currency in SMS. You get 160 before carriers split your text and double your costs. Here’s what works:
Front-load your offer (“50% off,” not “Hey there!”)
One link maximum (multiple links scream spam)
Skip emojis (they can cause messages to break)
Skip personalization if you’re tight on space — [Name] becomes “Christopher” and eats 11 characters you can’t spare
Segment your audience
Split your list before sending. Active customers receive your sales announcement, inactive customers receive your win-back offer, and top spenders receive VIP early access.
Three different bulk campaigns, three different groups, better results than one mass blast to everyone.
Schedule and send
Test SMS timing before committing to a schedule. Send 100-contact batches across different days and times, then track performance for 48 hours. Here’s what typically works:
9 AM to 12 PM for transactional updates and business messages
12 PM to 3 PM pulls lunch-break shoppers in retail and food
5 PM to 9 PM gets THE highest engagement for promotional content (9.4% click-through for automated messages)
Thursday, Friday, Saturday outperform the rest of the week
First and last days of each month see increased purchase activity
Scale up whatever gets you above 3% click-through rates. Below 1% means your timing’s off or your message needs work.

How can businesses use bulk SMS for marketing?
The best way to send bulk SMS is when you have a sale, promotion, or event to shout about that can encourage clicks and engagement.
Consider these opportunities:
Flash sales: 10 AM text with a 2 PM expiration. Four hours to buy or miss out completely.
VIP early access: Your top 20% of customers shop tomorrow’s launch today.
Back-in-stock alerts: Waitlisted that sold-out product? Text them the second inventory lands. These people have already decided to buy.
Event reminders: Last day for Christmas delivery, extended holiday hours, upcoming promotions.
Loyalty milestones: Skip the balance update and tell them what they can get: “50 points from a free coffee” or “One purchase from Gold status.”
Location-based offers: Segment your list by zip code and purchase history. Text the runners when running shoes go on sale, not everyone.
Combined strategy: Bulk SMS works for flash sales and product launches. Automated flows handle the individual stuff like welcomes and order confirmations. Both have their place in your overall messaging strategy.
“Bulk SMS is your best channel for time-sensitive promotions because people check texts routinely. Email gets buried, social media algorithms hide your posts, but SMS lands directly in pockets.”
Evaldas Mockus, VP of Growth at Omnisend
Successful brands using bulk SMS
Check out these bulk SMS results from successful brands:
Vagari Bags: Added SMS to email workflows, hitting 6-7% click rates on product launches. Quick texts about new arrivals generated 5x return on ad spend while story-driven emails built the brand.
Žalgiris Kaunas: Basketball club built 9,000 SMS subscribers for game-day alerts and merchandise drops. Email and SMS combined generated 39% of total revenue within one year.
Kerrits: Abandoned cart SMS pulled 15% conversion rates at $2.87 per message. Welcome emails (not SMS) hit $6.58 per send, helping it improve ROI across all channels.
Vape Superstore: Switched from Klaviyo to Omnisend for SMS features and saw mobile signup forms jump from 18% to 32% conversion. Used texts for clearance alerts and reward program updates to reach its predominantly mobile audience.
These results show that bulk SMS, combined with automations and additional channels such as email, can generate significant revenue for your business.
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
Start sending smarter bulk SMS campaigns
Bulk SMS generates measurable revenue that justifies its place in your marketing mix. The channel delivered $25 million for US brands in 2024, and if you want a slice, your SMS strategy needs mass texts alongside automations.
Test batches of 100 and track click-through rates with sales attribution to see what generates revenue. Try different character lengths, offers, timing, and segment your customers with the data bulk SMS generates for future targeting.
Omnisend lets you build standalone SMS campaigns for scheduled or immediate bulk sends, plus automations that trigger throughout your customer journey.

Mass texting is legal when you follow proper consent and TCPA/GDPR compliance requirements. Always get permission before sending marketing messages, provide clear opt-out instructions in your texts, and maintain an opted-in list.
3. Can I send bulk SMS for free?
No, there are no free bulk SMS services, although you might get bonus SMS credits as part of a paid plan. For instance, Omnisend’s Pro plan provides bonus SMS credits equal to the price of your monthly plan. That means you get $59 in SMS credits if your plan is $59/month.
4. Can I send bulk SMS in the USA?
Yes, provided you comply with spam regulations by obtaining explicit consent from recipients before sending promotional text messages. Bulk SMS marketing tools automatically handle regulatory requirements on the communication side.
5. How to send 1,000 messages at once?
Mass SMS marketing platforms make reaching thousands of contacts simple. Upload your contact list as a CSV file, compose a message, select your parameters (region, time, date), and your campaign will run based on your set conditions.
6. Is bulk SMS effective?
Very. Omnisend’s research shows that US brands generated over $25 million in SMS sales during 2024. It also found that automated messages deliver exceptional results — representing just 9% of sends but driving 18% of orders, with click rates 147% higher and conversion rates 118% better than standard campaigns.
