Are solo ads worth it? Sometimes, but only if your setup can show you what the traffic did. Many buyers can’t tell after an order whether it paid off, because nothing in their list or their links shows where subscribers and sales came from. Without that, a solo ad is a guess you pay for.

This page covers how buying a solo ad works, how to record each order, the mistakes that most often waste a budget, what to do instead, and a checklist to use before you buy any solo ad. Most of those mistakes are within the buyer’s control. Fixing them gives you better data, though it doesn’t guarantee profitable traffic.

What is a solo ad?

A solo ad is an email that another list owner (the seller) sends to their own list, promoting your link. You usually pay per click. The seller sends the email, and the clicks land on the page you chose.

For affiliate marketers, that page should be your opt-in page, not an affiliate offer. You’re buying a chance to get subscribers. After that, your own emails have to earn their trust.

Solo ads are common in the “make money online” niche, because many sellers have lists of people interested in that topic. That’s also the risk: those readers see a lot of offers.

How buying a solo ad on Udimi works

Udimi is a marketplace where solo ad sellers list their offers and buyers order clicks (Udimi calls them visitors). Per Udimi’s own help pages, as of Oct. 30, 2026 (how to buy, terms):

Go to Buy Solos and filter the sellers.
Open a seller’s profile to see ratings and average stats from their last 30 solos.
Choose how many visitors you want and a start date.
Pick optional filters, such as the Prime filter (3 cents per visitor), top tier only, or mobile or no mobile.
Paste your link or ad text and check out.
The seller has 24 hours to accept or reject, and 100 hours to deliver.

Click filtering. Udimi says its filter removes bots, duplicates, click rings, traffic exchanges, 3-second visits, proxies, VPNs and high-risk countries, and “only after passing all these filters, traffic is counted in your statistics” (click filter).

Refunds. Visitors not delivered within 100 hours are credited to your Udimi balance automatically. You can spend that credit on another order or ask for a refund to the card or PayPal account you paid with (Udimi says a card refund may take up to 14 days to appear on your statement; PayPal refunds appear right away). Payments older than 60 days, orders that were fully delivered, and orders where your link was broken or your site was down can’t be refunded (refunds, terms).

Fees. Udimi lists a click filtering fee: free for Prime account holders, $3 for others (Udimi fees).

Prices are set by each seller and vary a lot, so compare the cost per click across a few sellers before you order.

How to record each solo ad order

Keep one row per order and fill it in the day you buy, not weeks later. If you test more than one seller, label them A, B and C in your sheet. This is about the method, not any one seller.

Order	Clicks bought	Cost	Cost per click (cost ÷ clicks)
Seller A	clicks Udimi counted as delivered	what you paid, fees included	cost ÷ clicks
Seller B	same	same	same
Total	sum of all orders	sum of all orders	total cost ÷ total clicks

Sales: count only what you can trace

Every network: if your emails promote offers on more than one network, such as JVZoo and Explodely, check every account before you add anything up.
Network-reported only: count the sales the network reports, and take refunds off. A click is never a sale.
Link to the solo ad: count a sale for an order only if its tracking ID shows it came from that order’s subscribers or emails. Without tracking IDs, you can’t tell which subscriber or email made a sale.

If you can’t connect sales to an order, you can’t calculate a real return on it. All you can see is what you spent and some sales from an unknown source. That missing data alone is a good reason not to spend more yet.

What to watch in the subscribers

Be clear about what each number covers. Clicks are the visitors Udimi counted as delivered for one order. Subscribers are the people who joined through that order’s form or tag. Your list total mixes every source, including earlier sign-ups, so it can’t stand in for either.

How many of the order’s subscribers have never engaged with an email. A large silent share points to a mismatch between your gift and the seller’s list. Split this by seller, not just for the whole list.
Clicks per delivered email for that tag, over every send, plus unsubscribes and complaints. Use your autoresponder’s unique click count and note which count you used. Treat opens as secondary, even with bot and Apple Privacy filtering on.
How the first email does compared with the ones after it. If interest fades fast after the gift email, the follow-up isn’t matching what people joined for.

Put simply, divide emails delivered by clicks to see how many emails it takes to get one click. Watch that number as you change the gift and the sequence.

Cost per subscriber

You only get a reliable cost per subscriber if every sign-up is tagged by order. Without that, you have no opt-in count for the clicks you bought, and you can’t split your list by source. Order clicks and your whole list can’t be turned into a conversion rate either: they cover different things. That missing tag is first on the mistakes list below.

Common solo ad mistakes

No source tags. Every solo ad subscriber goes into the same list with no tag, so you can’t see which seller sent readers and which sent people who never open a thing.
A vague free gift. People who don’t know what they signed up for rarely read the next email.
Single opt-in. Anyone who types an email address is added. Nobody has to confirm. With paid clicks, that lets in typos, throwaway addresses and people who only wanted to see the page.
Too many emails to everyone. Daily promos to the whole list, with no segments and no preview text, mean new subscribers and silent ones get the same emails.
No tracking IDs on affiliate links. You can’t match sales to emails or to traffic sources.
Treating clicks as the goal. Clicks are easy to buy. What you need are readers.

Healthy technical checks, such as passing the compliance checks in Google Postmaster Tools, a low reported spam rate and nearly all mail accepted, don’t prove inbox placement, so they can’t rule out deliverability problems. When a list stays quiet despite clean technical numbers, the usual suspects are relevance, frequency and lead quality.

What to do instead

Fix the list before buying more traffic. If your current list is quiet, pause paid traffic until it’s in better shape. New subscribers would fade the same way.
Start with one seller and a small order, so a bad result costs little.
Use a specific gift that matches what the seller’s list joined for.
Give each order its own form or tag, so every subscriber shows where they came from.
Have the welcome sequence written and tested before the first click arrives. Our email list guide has a 5-email version with copy-ready first email.
Add a tracking ID to every affiliate link.
Set a break-even rule first (worked example below).
Judge on clicks and network-reported sales after a few weeks, not on the opt-in count on day one.

A break-even rule you can set before you buy

Write down three numbers before you pay:

Cost per subscriber = order cost ÷ new subscribers with that order’s tag.
Commission per sale for the product you plan to promote.
Sales you need per 100 subscribers to break even = (cost per subscriber × 100) ÷ commission per sale.

Worked example (hypothetical): if a test order brings subscribers at $2 each and the commission is $20 a sale, you need 10 sales per 100 subscribers just to get your money back. That’s an illustration only, not a typical result. If that number looks unrealistic for your list, don’t buy more until the welcome sequence and offers improve.

Checklist before you buy a solo ad

Your opt-in page works on phone and desktop.
Your gift is specific and fits the seller’s list topic.
Your welcome sequence is written, tested and switched on.
Your sending domain is authenticated (SPF, DKIM, DMARC). See our email list guide.
This order has its own form or tag.
Every affiliate link has a tracking ID.
You read the seller’s recent reviews and asked the seller:
- What did your subscribers sign up for?
- How often do you mail your list, and when did these subscribers join?
- How do you remove bounces and people who stop opening?
Must do: see and approve the seller’s ad copy before it goes out. The seller mails it to promote your page, and the FTC says that for a commercial email, “both the company whose product is promoted in the message and the company that actually sends the message” may be held responsible under CAN-SPAM. Letting the seller write or send the copy doesn’t remove your own exposure as the advertiser. Seeing it first is how you lower the risk: check that the subject line is honest, nothing in it is misleading, and it makes no income promises (FTC CAN-SPAM guide). If the seller won’t show it, don’t buy.
You read Udimi’s refund rules, including the 60-day limit and the “broken link” exclusion.
Your affiliate emails carry a clear disclosure, as the FTC’s endorsement guides FAQ explains.
You check your spam rate in Google Postmaster Tools. Google’s sender guidelines say to keep it below 0.10% and avoid reaching 0.30%.
You wrote down your break-even numbers.
The budget is money you can afford to lose.

Alternatives to try with the same budget

If you’re not ready for solo ads, these put the same money or time toward readers who chose your topic:

Write 3 or 4 helpful blog posts that answer the exact question your gift solves, with the opt-in form at the top and the end. Slow, but free.
Swap a mention with a list owner your size in the same niche: you each recommend the other’s free gift once.
Run a small paid search or social test to your opt-in page with a hard daily cap, tagged like any other source.
Spend the budget on your welcome sequence and gift first. A better gift lifts the results of every traffic source you add later.

So, are solo ads worth it? Our honest verdict

Not until you can measure them. If you can’t trace sales and engagement back to each order, you can’t know whether a solo ad paid off, and buying more only adds cost you can’t judge.

That doesn’t mean solo ads can’t work. A vague gift, no tags, no tracking and too many emails will make almost any traffic look bad, and most of those are buyer mistakes, not the sellers’.

Solo ads may be worth a small test for you if every box on the checklist is ticked and you treat the spend as the cost of a lesson. They’re probably not worth it yet if you don’t have a tested welcome sequence, tracking IDs and a way to tag each order.

FAQ

Are solo ads a scam?

Not by themselves. A solo ad is a paid email placement, and quality varies by seller. Read reviews, start small, tag each order and judge the results on clicks and sales, not sign-ups.

How much do solo ads cost?

Each seller sets their own price, and it varies a lot by seller and list, so compare a few before you order. On Udimi, the optional Prime filter adds 3 cents per visitor. Check current prices before you plan a budget.

Can I get a refund on Udimi?

For visitors that weren’t delivered within 100 hours, yes: Udimi credits your Udimi balance automatically, and you can then spend it or get a refund to the card or PayPal account you paid with. Fully delivered orders and payments older than 60 days can’t be refunded.

Should I send solo ad traffic straight to an affiliate link?

We don’t recommend it. Send it to your opt-in page so you can follow up. Most solo ad clicks won’t buy on the first visit, and without an opt-in you can’t reach them again.

How long should I wait before judging a solo ad?

Give your welcome sequence time to run, usually a few weeks. Then compare clicks per delivered email and network-reported sales for that tag against what the order cost.
