Best Solo Ad Vendors
Answer Buyers compare solo ad vendors by asking how the list was built, which niche it serves, and what past delivery proof looks like. They also compare send timing, reporting, and written refund rules. A stronger vendor explains limits clearly and answers questions before payment.
Compare list quality
Ask how the list was built. Ask which niche it serves. Ask what a past send looked like, in a sample you can actually read. A list of people who bought a similar offer is a different product from a list of people who grabbed a freebie. The vendor should be able to say which one you are getting. A slogan is not a list description.
Quality here means fit. A large claim you cannot check is weaker than a smaller description that names the niche and shows a sample creative.
Compare delivery and reporting
Compare when the email goes out, what number or placement is promised, and what report comes back. A single total, with no time and no way to match it to your own page, is a thin report. A log you can line up with your tracker is a stronger one. Ask which of those you will receive. Ask before you pay. The answer is part of the comparison, along with the price.
Compare refund terms
Read what is refunded, what is not, and when the seller treats delivery as started. Two quotes with the same price are different deals if one writes the refund rule and the other says to trust them. Get the rule in the quote. A vendor who explains the limit in plain language is easier to keep, and easier to leave.
