Solo Ads, Defined

A solo ad is an email sent by someone who owns an email list, promoting only your offer, which is where the "solo" comes from. You pay the list owner, usually per click, and their subscribers who are interested click through to your page. It's a way to rent access to someone else's audience while you build your own.

How Solo Ads Work

  1. You find a list owner (a "vendor" or seller) in your niche.
  2. You agree on a number of clicks and a price.
  3. You provide a link to your opt-in page, and sometimes the email copy.
  4. The seller emails their list.
  5. Subscribers click through, and some join your list.

Why Marketers Use Them

  • Speed: traffic within days, not months.
  • List building: visitors join your own email list.
  • Control: you choose how many clicks to buy.
  • Testing: a quick way to test opt-in pages and offers.

The Downsides

  • Quality varies: some sellers' traffic rarely converts.
  • Narrow niches: they work best for make-money-online, business and self-improvement offers.
  • Shared audiences: the same subscribers may see many offers.
  • Costs add up while you find good sellers.

What Solo Ads Cost

Most solo ads are priced per click, with each seller setting their own rate. A first test is often 100 to 200 clicks. What matters most is your cost per subscriber and whether those subscribers buy. See our Udimi pricing guide for how to budget.

Where to Buy Solo Ads

You can buy directly from list owners, but a marketplace is safer for beginners. Udimi is the largest solo ads marketplace, with seller ratings, reviews, click tracking and refunds if an order isn't delivered. Our guide on how to buy solo ads on Udimi walks through a first order.

What You Need Before Buying

  1. An opt-in page with a useful free offer.
  2. A follow-up email sequence.
  3. An offer to promote, such as an affiliate product or your own product.
  4. Tracking to see which sellers convert.

Rules to Follow

When you email people who joined your list, follow the FTC's CAN-SPAM guide: honest subject lines, a physical address and an easy way to unsubscribe. Disclose affiliate relationships when you promote products.

Are Solo Ads Worth It?

They can be, for the right niche and with a funnel that converts. Treat your first orders as tests, judge sellers by subscribers and sales rather than clicks, and scale only what works.
