Marketing automation cost in the US: the bill has four lines

Short answer: A US marketing automation bill has four lines: the subscription, texting, the build and the hours to keep it running. The plans we checked run from US$0 to US$497 a month. Once the carrier fee is added, a text costs about 1.2 to 1.3 cents per segment at Twilio’s list prices (our arithmetic), and registering to text is under US$50 in year one for a low-volume sender. Price all four lines before you pick a plan.

This article is a spoke of our US guide to marketing automation, and it covers the money only. Every price below was read on the source’s own page on October 10, 2026. Prices change, so confirm on the vendor’s page before you buy.

Why the advertised price is the smallest part of the answer

The number on a pricing page answers “what does the plan cost”. It does not answer “what will I pay”.

A US bill has four lines:

• The subscription, and what happens when you pass its contact limit.
• Texting, which carries a carrier fee on every segment plus registration.
• The build.
• The hours it takes to keep it running.

The plan is the first line only. In the example later on, it is under a quarter of the first year’s cost.

Depending on your state, sales tax may be added to a software subscription, and your invoice will show it. For the wider budget around all of this, see US digital marketing costs.

Line one: the subscription, and what happens at the limit

The plans we checked in October 2026 span a wide range. Mailchimp and Klaviyo both offer free plans at US$0 a month. GoHighLevel lists Starter at US$97 a month, Unlimited at US$297 and Agency Pro at US$497, with a 14-day free trial. The upper tiers are aimed at agencies running client accounts.

HubSpot and ActiveCampaign price on contacts and seats. For which platform fits, read our comparison of marketing automation software for US small business. That article owns “which one”. This one owns “what it costs”.

The real question is what happens at the limit. The Mailchimp pricing page shows a Free plan limited to 250 contacts, with sends capped at 500 a month or 250 a day. It states that sending will be paused if the contact or email send limit is exceeded. On paid plans, the page’s FAQ says Mailchimp will automatically bill you for your overages.

On the free plan you hit a wall. On a paid plan you hit a bigger invoice.

The Klaviyo pricing page describes its free plan as covering up to 250 active profiles, 500 emails a month and US$5 of mobile messages a month. Past the limit, the account will no longer be able to send additional emails or messages until the next billing cycle, and you are prompted to upgrade.

Before you sign, ask the vendor in writing what the bill is at double and at triple your list, and whether passing a limit pauses sending or raises the bill.

Line two: every text carries a carrier fee

Every outbound text pays the platform and pays a carrier, and the carrier charge applies to every segment.

Twilio is a messaging provider that publishes its US prices in full, which makes it a useful reference. Your platform sets its own rates, which may be higher.

On Twilio’s US SMS pricing page, which states that pricing is current as of October 2026, a text from a 10-digit long code costs US$0.0083 per segment to send and US$0.0083 to receive. The carrier fee on each outbound segment depends on the network the recipient uses. A picture message is more: outbound MMS is US$0.022 per message before carrier fees.

Here is the per-segment arithmetic for outbound texts. The totals are ours.

Carrier	Twilio’s price	Carrier fee	Total per segment
AT&T	US$0.0083	US$0.0035	US$0.0118
T-Mobile	US$0.0083	US$0.0045	US$0.0128
Verizon	US$0.0083	US$0.005	US$0.0133

That is about 1.2 to 1.3 cents a segment. Send 2,000 one-segment texts a month and the bill is US$23.60 to US$26.60.

The word to watch is segment. Twilio’s SMS character limit page explains that one segment holds 160 characters in the standard GSM-7 alphabet. A single emoji or other Unicode character switches the message to UCS-2, where the limit is 70. Longer messages are split into segments of 153 characters (GSM-7) or 67 (UCS-2).

You are billed per segment, not per message. A 100-character text is one segment when it is plain and two segments with an emoji in it. The same 2,000 texts become 4,000 segments, which is US$47.20 to US$53.20 on the same arithmetic. One emoji, double the bill.

What registering to text costs before you send one

Before a business can send texts from an ordinary 10-digit number, it has to register. The US system is called A2P 10DLC, and registration goes through The Campaign Registry. The fees below come from the Twilio Help Center article on A2P 10DLC pricing. The registry raised some of them on August 1, 2025. Twilio says carriers charge these fees and Twilio passes them through to customers with no added cost.

You register a brand and a campaign:

• Brand. A Sole Proprietor brand or a Low Volume Standard brand costs US$4.50 one time. Low Volume Standard needs a tax ID (EIN) and suits fewer than 6,000 messages a day. A Standard brand costs US$46 one time and includes secondary vetting.
• Campaign. There is a US$15 vetting fee, then a monthly fee: US$1.50 for a low-volume mixed use case, US$2 for Sole Proprietor and US$10 for a standard use case.

Toll-free numbers and short codes sit outside this system.

Our arithmetic for a first year, Low Volume Standard brand with a low-volume mixed campaign: 4.50 + 15 + (12 x 1.50) is US$37.50. With a standard use case campaign at US$10 a month, it is 4.50 + 15 + 120, or US$139.50. Your platform may add its own setup charge on top, so ask.

Registration is not a legal opinion on consent. Whether you may text someone at all is a separate question, and state texting laws covers it.

Line three: someone has to build it

Software that can send a sequence is not a sequence that works. A done-for-you build of a single automation runs US$2,500 to US$6,000, and more for a system that connects several tools. That is the range we publish in our US guide, not market data.

The money buys mapping the workflow, writing the messages, connecting the form and calendar, consent capture and testing. Doing it yourself costs hours instead of dollars, which is a poor trade if those hours would otherwise go to paying work. Our AI automation service covers having it built for you.

Line four: the hours it takes to keep running

An automation is not finished when it goes live. The hours go on checking that sequences still fire, pruning bounced and unsubscribed contacts, updating offers and hours, and reading the results.

Price those hours. The Bureau of Labor Statistics Employer Costs for Employee Compensation release for June 2026, released September 9, 2026, puts total employer compensation for private industry workers at an average of US$46.89 per hour worked. Wages are US$32.82 of that and benefits US$14.07. This is an all-private-industry average, not a marketing wage, so use it as a yardstick and not as a quote.

Our arithmetic: two hours a month is 24 hours a year, and 24 x 46.89 comes to about US$1,125 a year.

A hypothetical Boise veterinary clinic, year one

This is a hypothetical built to show the method, not a client, and it has no measured results. A two-vet clinic in Boise, Idaho has 1,800 contacts. It wants appointment reminders by text and a lapsed-patient email sequence.

The assumptions, so you can swap in your own:

• It picks GoHighLevel’s Starter plan at the listed US$97 a month.
• It sends 600 one-segment reminder texts a month.
• Texts are priced at Twilio’s published rates, using the Verizon total of US$0.0133, because we did not check the platform’s own rate and it may be higher.
• It registers a Low Volume Standard brand with a low-volume mixed campaign.
• It pays US$2,500 once for the build, the low end of our range.
• It spends two hours a month of staff time, priced at the BLS average.

The GoHighLevel pricing page says usage-based charges apply to email and SMS marketing and calling, covering phone numbers, SMS, emails sent and premium AI usage. We did not read its per-text rates, which is why the example uses Twilio’s.

Line	Year one	Year two
Subscription (12 x US$97)	US$1,164.00	US$1,164.00
Texts (7,200 segments x US$0.0133)	US$95.76	US$95.76
10DLC registration	US$37.50	US$18.00
Build	US$2,500.00	US$0
Upkeep (24 hours x US$46.89)	US$1,125.36	US$1,125.36
Total	US$4,922.62	US$2,403.12

Read it three ways. The subscription is under a quarter of year one: 1,164 divided by 4,922.62 is about 24%. The texts everyone worries about come to under US$100 a year at this volume. And upkeep costs about as much as the software.

Three ways the bill grows without anyone deciding it should

An emoji doubles your segments. A smiley in a reminder pushes a 100-character text from one segment to two, because the limit drops from 160 characters to 70. Keep reminders plain and count characters before you send.

Your list passes a contact limit. On Mailchimp’s paid plans, the page’s FAQ says it will automatically bill you for overages. A good month of sign-ups can raise the bill. Check your contact count before a big promotion.

Usage-based charges sit on top of a flat plan. GoHighLevel’s page says usage-based charges apply on top of the plan price. Ask for per-text, per-email and phone number rates in writing before you commit.

When the right spend is zero

Three signs say you should spend nothing yet.

Your list is small enough to email personally. A personal note usually lands better than a sequence.

You have no record of who agreed to what. If you cannot show how a contact opted in, fix that first.

Nobody has the two hours a month. An automation nobody maintains drifts out of date and sends the wrong thing to the right people.

A free plan is a fair way to test one idea. Mailchimp’s Free plan allows 250 contacts and Klaviyo’s covers up to 250 active profiles, enough to see whether one welcome email or reminder does its job. Remember the limits: sending pauses on one and stops until the next billing cycle on the other.

Frequently asked questions

How much does marketing automation cost per month in the US?

Plans we checked in October 2026 run from US$0 to US$497 a month, and the plan is only one of four lines. The other three are texting, which carries a carrier fee on every segment plus registration, the build, and the hours to keep it running. Prices change, so confirm on the vendor’s page, and ask what the bill becomes when your list passes the plan’s contact limit.

How much does it cost to send a marketing text in the US?

At Twilio’s list prices in October 2026, a one-segment text sent from a 10-digit number costs US$0.0083 plus a carrier fee of US$0.0035 to US$0.005, which is about 1.2 to 1.3 cents (our arithmetic). Your platform sets its own rates and may charge more. You pay per segment, not per message, so a long text or one with an emoji costs more.

What does 10DLC registration cost?

Twilio’s published pass-through fees for a low-volume sender are US$4.50 once for the brand and a US$15 campaign vetting fee, then US$1.50 a month for a low-volume mixed campaign. Our arithmetic puts year one at US$37.50. A standard use case campaign at US$10 a month brings year one to US$139.50. Your platform may add its own setup charge, so ask.

Why did my texting bill go up when I sent the same number of messages?

Check your segments. One segment holds 160 characters in the standard alphabet, but a single emoji switches the message to a set where the limit is 70. A 100-character text is one segment plain and two with an emoji, so the same 2,000 texts become 4,000 segments. You are billed per segment, not per message.

Is a free marketing automation plan really free?

A free plan costs US$0 a month, but it has limits. Mailchimp’s Free plan is limited to 250 contacts and pauses sending when a limit is exceeded, and it does not include SMS. Klaviyo’s free plan covers up to 250 active profiles and stops sending until the next billing cycle. It is a fair way to test one idea, not to run a business.

What does it cost to have marketing automation set up for me?

A done-for-you build of a single automation runs US$2,500 to US$6,000 by the range we publish in our US guide, and more for a system that connects several tools. That is our range, not market data. The money buys workflow mapping, message writing, form and calendar connections, consent capture and testing. Doing it yourself costs hours instead of dollars.
