How Klaviyo Bills Customers for SMS

Last updated at:


If you've decided to start using Klaviyo to send text messages to subscribers, the next step is to set up your plan. The billing structure for SMS is primarily based on two criteria:

- The number of profiles, specifically how many you've sent text messages to per month
- The number of text messages you send per month

When you set up SMS in Klaviyo, your first number is free of charge, and an appropriate sending number is included in each plan. The only time you would need to pay for a number is if you choose to use a vanity code, or if you want to use a short code when it’s not included in your plan.

This article breaks down SMS billing, such as plan information and the included sending numbers.

Understand Your Monthly SMS Billing Plan

To find your billing plan, click the dropdown menu next to your account name and then clicking Account.


In the Overview tab, you can review your SMS plan, including how many:

  • Profiles and messages are allowed in your SMS plan
  • Profiles you have sent to within this billing cycle
  • Text messages (SMS and MMS) you have sent within this billing cycle


You will reach your plan's limit when you have either hit the maximum number of profiles or sent the maximum number of SMS messages, whichever comes first. 

If you are nearing your plan limits, you can choose another plan to keep sending. Simply click Upgrade Plan in the bottom right.

SMS and email are billed separately in Klaviyo. If you want to update your email plan, navigate to Billing > Email instead. Head to our article on How Klaviyo Bills Customers for Email for more information.

Cost of Messages

The number of sends a text counts as depends both on whether the message is an SMS or MMS as well as where the message is sent to. The table below breaks down the number of sends for each message type per region. 

US 1 send 3 sends
Canada 1 send 3 sends
UK 3 sends N/A
Australia 3 sends N/A

Note that certain keyword responses and double opt-in confirmation messages do not count toward your plan.

Choose Your SMS Plan

To see all available SMS plans, go to Billing > SMS. Here, you’ll see a breakdown of the different SMS plans, shown below.


Click Change to switch to another plan that fits your needs. When trying to decide which plan is right for you, account for: 

  • SMS or MMS messages in flows
  • The number of campaigns you plan to send per month
  • MMS messages counting as three sends 

The plan you chose will go into effect immediately in your account — not at the end of the billing cycle. Like email, if you change your plan in the middle of the month, the cost will be prorated.

We do not refund downgrades, as stated in our Terms of Service. Additionally, downgrading takes effect immediately, just as it would if you upgrade. The prices listed in the image above or in the product do not include sales tax.

Sending Numbers

All plans come with a free sending number. For instance, the free plan provides you with a toll-free number. As you increase your plan, you’ll gain additional throughput before applying for a short code. Note that the short code won't be available immediately. Further, there is an application process for short codes, and not all industries/businesses will be eligible. 

If you want a short code before it becomes included in your plan, you will have to pay for this on a monthly basis. Further, vanity short codes are not included and need to be bought separately. The prices for both are shown below.

Number Type Cost
Short code (random) $1,000/month
Vanity short code $1,500/month

SMS Credit Card Details

You can only have one credit card per Klaviyo account. If you pay for SMS using a different credit card than for email, it will change the default credit card for your account. The account owner will be notified via email if a payment fails.
