SMS Flows
Up to three automated text message flows added to your email setup, written short and tested on a real phone.
Some customers read every text and ignore most emails. SMS Flows adds automated text messages to Email Flows Build or Email Campaigns, in Klaviyo or a similar tool. We build up to three flows, such as welcome, abandoned cart and post-purchase. Messages are short, include opt-out wording, and are test-sent to a real phone before anything goes live.
- Up to 3 automated SMS flows built and switched on
- SMS sign-up set up using your own consent wording
- Every message test-sent to a real phone first

What it is
SMS Flows is a one-time add-on for Email Flows Build or Email Campaigns. It adds up to 3 automated SMS flows, such as welcome, abandoned cart and post-purchase, in Klaviyo or a similar tool. We write short messages with opt-out wording, set up SMS sign-up using your consent wording, and test-send everything to a real phone.
Why businesses buy it
Text messages are personal, so they need more care than email. A badly timed text, or one sent without clear consent, can do more harm than good. Many stores switch on SMS, send a few campaigns and stop, without ever building the flows that run quietly in the background. SMS Flows builds up to three, planned to work with your emails rather than repeat them. You stay in charge of consent rules and costs. Results are never guaranteed, and your platform's reports show how each flow performs.
Problems this solves
Abandoned cart and welcome messages rely on email alone
We add up to 3 automated SMS flows, such as welcome, abandoned cart and post-purchase, in Klaviyo or a similar tool. Short texts then reach customers alongside your existing emails.
Phone numbers are collected without clear consent wording
We set up an SMS sign-up form or keyword using your consent wording, and every message carries opt-out wording. Legal review of your consent rules stays with you.
Texts arrive cut off or broken on real phones
Every message is written short for its flow, then test-sent to a real phone before switching on. You see exactly what customers will receive, and a written handover report explains each flow.
A good fit if
You run an online store and already use, or are buying, Email Flows Build or Email Campaigns.
Your email platform supports SMS, such as Klaviyo or Omnisend, and you have switched it on.
Some of your customers would rather get a short text than another email.
You know your consent wording and opt-in rules, or will get them confirmed before launch.
Not the right fit if
You do not have Email Flows Build or Email Campaigns. This add-on is offered only with them.
You want one-off SMS promotions rather than automated flows. SMS campaigns are not included; note them at checkout for a Change Quote.
You need another email flow, not SMS. See Extra Email Flow.
You want your consent rules reviewed for legal compliance. That needs your own legal adviser, as legal review is not included.
How it works
- You switch on SMS in your platform, register a sending number in your account, and share your consent wording and opt-in rules.
- We plan up to 3 SMS flows, choosing triggers and timing that sit alongside your email flows rather than repeating them.
- We write short, clear messages for each flow, with opt-out wording, and you review them with 2 rounds of revisions.
- We set up an SMS sign-up form or keyword using your consent wording, and build the flows in your platform.
- Every message is test-sent to a real phone before the flows go live, and a written handover report explains how they work.

Expected benefits and how to measure them
- Helps you reach shoppers who tend to miss or ignore email.
- Makes it easier to grow an SMS list on clear consent terms.
- SMS subscribers
- Track SMS sign-ups in your email platform at the end of each month after launch.
- Recovered carts
- Compare orders attributed to your cart flows in the platform report before SMS was added and after.
- Opt-outs per flow
- Check unsubscribes in each SMS flow report monthly to make sure the messages are welcome.
Before you start: Before launch, note any SMS subscribers you already have. Record monthly orders from your email cart flow.
These are things to track, not promised results. Outcomes depend on your data, your team and your market.
Running costs
SMS has a real running cost: sending fees billed by your platform per message, which vary by country. Any number registration fees are also billed to you by your platform. Keeping messages short and flows focused helps keep these costs under control.
Ask about running costsCustom requirements
Add a note at checkout if you need something specific. If it fits within the Scope Card it is simply included. If it goes beyond it, you get a written Change Quote within two working days, and that work starts only once you accept it, with its time added to your delivery date.
Request a custom versionKeep it running
Once live, the SMS flows run on their own. The written handover report shows your team how to pause or edit them. If you bought SMS Flows with Email Flows Build, its post-launch support covers them, and the optional Upmark maintenance after that can look after them with your email flows, including monitoring, fixes and change hours. Otherwise, later changes are quoted through a Change Quote.
How this compares
| Do it yourself with a SaaS tool | Hire a custom agency | Upmark Labs | |
|---|---|---|---|
| Cost | Your time learning SMS rules and the flow builder | Often a separate SMS retainer | One fixed price shown before you buy, with sending fees paid to your platform |
| Scope | One flow, if time allows | Agreed in a proposal | Up to 3 SMS flows, fixed before you buy |
| Consent | Sign-up added without much thought | Varies | SMS sign-up set up using your consent wording |
| Testing | Rarely tested on a phone | Usually tested | Every message test-sent to a real phone before launch |
Questions about this product
Which packages can SMS Flows be added to?
Email Flows Build and Email Campaigns. With Email Flows Build, the SMS flows sit alongside your welcome, abandoned cart and post-purchase emails. With Email Campaigns, they add automated texts to a program that already sends regular campaigns. Either way, they are built in the same email platform, as long as it supports SMS.
Which platforms can run the SMS flows?
Klaviyo and Omnisend are the most common, and they connect with Shopify and WooCommerce. Other email platforms with built-in SMS may work too. SMS needs to be switched on in your account, with a sending number registered, before we start. If you are unsure whether your platform supports it, ask before ordering.
Do SMS Flows make our text messages legally compliant?
No. We set up SMS sign-up using the consent wording and opt-in rules you give us, and every message includes opt-out wording. But consent rules differ by country, and checking them is a legal matter. Please have your own adviser confirm your wording. Legal review is not included in this add-on.
How much does it cost to send the SMS messages?
That depends on your platform and your customers' countries. Your platform bills sending fees per message, and some countries cost much more than others. Number registration may carry its own fee. These costs are billed to you directly by the platform, and we keep messages short to help control them.
Can you register our SMS sending number for us?
No, the number is registered in your own account, and the approval is decided by the platform and the phone carriers. Registration usually asks for business details only you can confirm. We can point you to the right place in your platform, but the paperwork itself is not included in SMS Flows.
Will SMS messages annoy customers who already get emails?
Not if the flows are planned well. We time the SMS flows to work alongside your emails rather than repeat them, and every message is short with clear opt-out wording. Only people who opted in to SMS receive texts. You approve every message, with 2 rounds of revisions, before anything goes live.
What happens after the SMS flows go live?
They run automatically, and you keep everything we built. The written handover report shows how to pause or edit each flow. If you bought them with Email Flows Build, they are covered by its post-launch support. Later changes, or new SMS flows, can be handled through optional maintenance or a Change Quote.

Add SMS Flows to Email Flows Build or Email Campaigns for up to three automated text flows, written short and tested on a real phone.
