🎯 The business: you set up and run the automatic emails and texts that small online shops know they should have and never finish: a welcome series, abandoned-cart reminders, after-purchase messages and win-back notes, plus a regular campaign. You build them in the shop’s own email platform, make sure every address and phone number was collected with proper consent, and tune them every month. Shop owners pay a one-time build fee and a monthly retainer.

Is this for you?
It suits a clear writer who also likes setting things up and checking that they work: does the cart email fire after one hour, does the discount code exist, does "STOP" really stop? You do not need to code. You do need patience with details and respect for rules, because texting mistakes can cost a client real money.
AI writes subject lines and email drafts in seconds now, and the email platforms build AI into their own editors. So writing alone sells for less every year. What holds its value is the setup: the right flows, clean consent, working triggers, sensible timing, testing, and reading the results honestly. If you want to write copy and nothing else, this is getting crowded. If you like the whole system, it is steady work.
Who pays, and what
Small online shops on Shopify, WooCommerce and similar platforms selling clothing, skin care, coffee, pet supplies, crafts and gifts. Also local businesses with repeat customers and a list they never use: salons, gyms, bakeries that take online orders. Most have an email platform installed and two half-built flows.
What they pay, as estimates from the offers seen: about $500 to $3,000 to build a set of flows and $500 to $2,000 a month for ongoing management. Upwork’s November 2026 rate guide shows marketing automation consultant profiles at $40 to $90 an hour, a global range. No survey of these prices was found, so treat them as ranges.
What it takes to start
| A practice account: Klaviyo’s free plan (up to 250 active profiles and 500 email sends a month, per its pricing page, Nov 2026) with a free test store | $0 |
| One paid AI account for drafting (Claude Pro, ChatGPT Plus or Gemini AI Pro; about $20 a month) | $0 to $240 |
| LLC or sole proprietor setup and local license | $0 to $300 |
| Errors and omissions insurance (an estimate; get quotes) | $0 to $500 |
| Domain and business email, set up with SPF, DKIM and DMARC | $20 to $60 |
| All-in | ≈ $20 to $1,100 |
Clients pay for their own email and texting platform, in their own name, so their lists and history stay with them. Paid tiers rise with list size; check the vendor’s current price for each client.
Start to finish: the steps
1. Learn one platform properly. Klaviyo is common with Shopify shops; Mailchimp and others are common elsewhere. Build all four core flows in a free test account, including the triggers and conditions, and send yourself every email.
2. Choose a kind of shop. Skin care, coffee, pet products, apparel. Each has its own buying rhythm, which decides when a win-back email should go out.
3. Set up the business. Register, open a business bank account, price insurance, and use a written agreement covering access, who approves messages, data handling and what happens to the account if you part ways. See contracts, client data and AI rules.
4. Start with a paid audit. Check where each subscriber came from and whether consent was recorded, whether the sending domain is authenticated (SPF, DKIM, DMARC), which flows exist and whether they fire, and the unsubscribe and complaint rates. Hand back a page of fixes in order.
5. Fix sending basics before writing anything. Authenticate the domain, add one-click unsubscribe, remove addresses that never open or that bounced, and stop any bought or scraped lists. Good emails sent from a damaged domain land in spam.
6. Build the four core flows. Welcome first, then abandoned cart, after purchase and win-back. Draft with AI, then rewrite in the brand’s voice and check every claim, price and code. A review request in the after-purchase flow goes to every buyer, with no reward for a good rating.
7. Add text messages only with real consent. A separate sign-up for texts, with the required disclosures, a registered sending number, and STOP tested. Fewer, more useful texts than emails.
8. Run a simple campaign calendar. One or two emails a week tied to real events: new stock, a restock, a season, a story about the maker. No fake countdowns or "only 2 left" that is not true.
9. Report honestly. Monthly: revenue the platform attributes to each flow, with a note that platforms count a sale if someone opened or clicked within a window and may have bought anyway; plus unsubscribes, spam complaints and list growth.
10. Grow. Add segmentation, a second platform, or a monthly newsletter service. Shop owners who trust you will ask about their website and ads next.
Pricing
| Paid audit: consent, sending setup, existing flows | $300 to $500 |
| Build of the four core flows, tested | $1,200 to $2,500 |
| Text-message setup add-on: consent forms, registration help, two text flows | $400 to $800 |
| Monthly management: four to six campaigns, flow tuning, report | $500 to $1,200 a month |
These are example prices within the estimates above. Never promise a revenue figure or a percentage lift; results depend on the shop’s products and list, and the FTC has acted against sellers who promised results they could not support. More in Pricing AI and IT services.
The math
Take three shops on a $700 monthly retainer ($2,100), plus one $1,800 flow build every other month, which averages $900 a month. That is $3,000. Costs run about $40 for AI and software, $40 set aside for insurance, $60 in payment fees and $40 for marketing, $180 in all, leaving about $2,820 before tax. The time is about 10 hours a month per retainer (30), 10 hours a month on builds averaged, and 6 hours of sales and admin, 46 hours in the month: roughly $61 an hour.
Set aside a quarter to a third of profit for income and self-employment tax. See Small business taxes.
Getting customers
Who to approach first. Shops you already buy from online, small brands run by people you know, and local businesses that collect emails at the counter and never send anything. You can sign up for their list today and see exactly what is missing, which makes your first message specific.
The first ten customers. Sign up for the email lists of 40 small shops in your niche and add an item to the cart without buying. Note who sends a welcome, who sends a cart reminder, and how good they are. Write to the 25 with the clearest gaps, with a short note on what you saw. Expect 4 to 6 replies, 2 or 3 calls and 1 or 2 paid audits. Repeat monthly and ask for referrals; ten clients within a year is realistic.
Hi Lena, I joined the Fernwood Tea email list last week and left two tins in my cart. Your welcome email arrived and looked lovely, but nothing came about the cart, and there was no second welcome email telling me which tea to start with. I set up these automatic emails for small shops on Shopify and Klaviyo, using your own account and your brand’s voice, and I check that every subscriber was collected with consent. I’d be glad to do a short paid audit of your setup, credited toward any build, or just answer questions on a 15-minute call. Either way, the cart reminder is worth turning on this week.
Channels, best to worst, for this customer.
| 1. Direct notes after testing their store | Specific gaps you found yourself are the strongest opener. |
| 2. Referral partners | Shopify web designers, product photographers and bookkeepers for online shops see the gap and do not want the work. |
| 3. Platform partner directories | Email platforms and Shopify list service partners; worth joining once you have a few clients. |
| 4. LinkedIn | Founders of small brands are there; share before-and-after flow maps. |
| 5. Maker and shop-owner groups | Online groups for Etsy and Shopify sellers; answer questions, follow each group’s rules. |
| 6. Upwork and Fiverr | Steady demand for Klaviyo work, with global prices. |
| 7. Google Business Profile | Helps only with local clients. |
| 8. Paid ads | Last. Never cold email bought lists; it is what you teach clients not to do. |
Turning clients into case studies and referrals. After 90 days, with permission, show the flows you built, the platform’s attributed revenue with its caveat, and the drop in spam complaints or bounces. Shop owners know other owners from markets, wholesale shows and online groups; ask for one introduction and offer a free audit to whoever they name. More in the launch and marketing playbook.
Running it week to week
Each week, check every client’s flows for errors and paused triggers, and look at bounce and complaint rates; if spam complaints climb toward Gmail’s limit, stop campaigns and find out why. Send scheduled campaigns only after a test to yourself on a phone. Keep a log of every flow, discount code and change. Once a month, write the report and suggest one test (a subject line, a timing change) for next month.
Rules to check
Email, CAN-SPAM: no false sender or subject line, identify the message as an ad, include a valid postal address, give a clear way to opt out, and honor opt-outs within 10 business days. The FTC says both the shop and the person who sends the email can be held responsible, and penalties reach $53,088 per email. Gmail and Yahoo have required bulk senders since 2024 (for Gmail, about 5,000 or more messages a day) to authenticate their domain, offer one-click unsubscribe and keep spam complaints below about 0.3%. Texts, TCPA: marketing texts need the person’s prior express written consent, and the consent form must say that consent is not a condition of buying. Since April 2025 the FCC requires that opt-outs sent by any reasonable means, not just "STOP," be honored within 10 business days. Send only between 8 a.m. and 9 p.m. in the recipient’s time zone. People can sue for $500 per unlawful text, up to $1,500 if willful, and some states, such as Florida and Oklahoma, add their own texting laws. Carrier registration: business texts from ordinary 10-digit numbers must be registered with the carriers (A2P 10DLC). Through Twilio, for example, that is $4.50 one-time for a sole-proprietor brand or $46 for a standard brand, $15 to vet each campaign, and $2 to $10 a month per campaign; many email platforms handle the sending number and registration for the client. Reviews: under the FTC’s review rule, review requests may not reward positive ratings. AI voices: if a client wants automated voice calls, the FCC ruled in 2024 that AI voices count as artificial voices, which need prior consent. Taxes: net self-employment earnings of $400 or more mean filing and self-employment tax.
What goes wrong
A client imports a list "from an old system" with no consent record, sends to it, and the domain lands in spam for months; refuse until you know where the addresses came from. A text campaign goes out at 7 a.m. to the West Coast; schedule by the recipient’s time zone. A discount code in a flow expires and customers complain; log every code with its end date. The platform’s attributed revenue looks huge and the owner thinks you doubled sales; explain attribution before they quote it to anyone. And a client cancels after the build; sell the retainer as tuning and campaigns, with a monthly report that shows the work.
Questions people ask
How much does it cost to hire someone to set up Klaviyo flows?
As estimates from offers seen, building a set of core flows runs about $500 to $3,000 and monthly management $500 to $2,000. Upwork’s 2026 rate guide shows marketing automation consultants at $40 to $90 an hour worldwide.
Is it legal to send marketing text messages to customers?
Yes, with prior express written consent, a clear way to opt out that you honor, sending hours of 8 a.m. to 9 p.m. local time, and a sending number registered with the carriers. Buying a phone list or texting people who only gave you their number for a receipt is how businesses get sued.
Which email flows should a small online store set up first?
A welcome series, an abandoned-cart reminder, an after-purchase series and a win-back email, in that order. They write only to people who already showed interest and keep running once they are built.
Can I buy an email list for my business?
Do not. Bought lists bring spam complaints that damage the domain for every future email, and Gmail and Yahoo now enforce complaint limits on bulk senders. Grow the list with sign-up forms instead.
Can a college student do email marketing for shops part time?
Yes; builds and campaigns are deadline work that fits around classes. International students on F-1 visas generally cannot freelance for outside clients without work authorization; check with your international student office first. More in the guide for students: visas, taxes, campus rules.
Free help
The FTC’s "CAN-SPAM Act: A Compliance Guide for Business" is short and clear. Google’s and Yahoo’s sender guidelines explain the bulk-sender rules. Email platforms, including Klaviyo, run free courses and certifications. Your texting provider’s help center walks through 10DLC registration. SCORE mentors and your local Small Business Development Center help with pricing and contracts at no cost.
Checked in November 2026: the FTC’s CAN-SPAM guide and penalty, Klaviyo’s free plan, Twilio’s 10DLC fees (in effect since August 2025) and the FCC’s opt-out rule. Texting rules are changing: part of the FCC’s consent-revocation rule was postponed and may be revised, so re-check the TCPA rules and carrier fees before each new texting setup.
