Bulk SMS Service: How to Choose the Right Provider for 100,000+ Texts

What a bulk SMS service does, what it really costs at volume, and the five questions to ask before you pay anyone.

QUICK VERDICT

Sending 100,000 texts or more in occasional campaigns? A managed bulk SMS service with one price per campaign costs a fraction of per-message platforms. Smarterblast: $449 for 100,000 texts, $699 for 500,000, $999 for 2,000,000, with a 70% delivery guarantee.

What Is a Bulk SMS Service?

A bulk SMS service sends one text message to thousands or millions of phone numbers in a single campaign. Each recipient gets it as an ordinary text, in the same inbox as messages from friends and family, with no spam folder or promotions tab in the way. That is why real estate, solar, insurance, mortgage and political campaigns lean on SMS when they need a big list to act quickly.

Bulk SMS services differ from everyday business texting apps in three ways:

What a Bulk SMS Service Really Costs

Per-campaign versus per-message bulk SMS pricing at high volumes

The headline price per text is the number most providers show you. The number that matters is the total for your campaign:

Campaign sizeAt $0.01 per textAt $0.025 per textSmarterblast
100,000 texts$1,000$2,500$449 (Bronze)
500,000 texts$5,000$12,500$699 (Silver)
2,000,000 texts$20,000$50,000$999 (Gold)

At 500,000 texts our Silver package works out at about $1.40 per 1,000 messages, against $8.30 per 1,000 at Twilio's published per-segment rate before carrier fees. Per-message platforms also tend to add monthly plans, number rental and carrier surcharges on top. The pricing page shows the cost per 1,000 at every tier.

Pick per-campaign pricing if you send 50,000+ texts at a time, your volume varies from campaign to campaign, or you run campaigns for clients.

Pick per-message pricing if you send small batches every week and need two-way conversations with each customer.

How to Choose a Bulk SMS Service: 5 Questions to Ask

  1. What does my whole campaign cost? Ask for the total for your list size, including every fee. If the answer needs a calculator, expect the bill to grow.
  2. What happens if delivery is poor? Most providers simply keep your money. Ask whether there is a delivery guarantee and what it covers. Ours: if fewer than 70% of the valid numbers on your list are delivered, we refund the package price.
  3. Will I get a delivery report? You should see how many messages were delivered, from the carrier reports, after every send.
  4. How much work is it for me? A self-serve platform means an account to set up, numbers to manage and every send to run yourself. A managed service means you hand over a list and a message.
  5. How fast can it launch, and who answers when I have a question? Ask how long a campaign of your size takes from payment to send, and send a question before you buy to see how quickly a real person replies.

Frequently Asked Questions

What is a bulk SMS service?

A bulk SMS service sends one text message to a large list of phone numbers in a single campaign. Each person receives it as an ordinary text from you. Self-serve platforms give you software to run the send yourself; a managed service like Smarterblast takes your list and message and runs the send for you.

How much does a bulk SMS service cost?

Per-message platforms typically charge around $0.01 to $0.025 per text plus carrier fees, which is $1,000 to $2,500 for 100,000 messages. Smarterblast charges one price per campaign: $449 for up to 100,000 texts, $699 for up to 500,000 and $999 for up to 2,000,000. At 500,000 texts that is about $1.40 per 1,000.

What is the best bulk SMS service for 100,000+ texts?

For occasional large campaigns, a managed service with per-campaign pricing usually costs far less than a monthly platform billed per message, and you do not have to learn any software. For frequent two-way texting with a small list, a self-serve platform is the better fit.

Is there a delivery guarantee?

Yes. Every Smarterblast package carries a 70% delivery guarantee: if fewer than 70% of the valid numbers on your list are delivered, according to the carrier delivery report, we refund the package price.

Do I need to send my list before paying?

No. Choose a package and pay in crypto. Once payment is confirmed we email you a private link to upload your list and message, and we agree the launch timing with you.

Do you send outside the US?

Yes. Smarterblast sends bulk SMS campaigns worldwide. Tell us where your contacts are when you upload your list.
