The reply using a specific template rule in the Rules Wizard sends your automated reply only once to each sender during a single session. This rule prevents Outlook from sending repetitive replies to a single sender from whom you receive multiple messages. During a session, Outlook keeps track of the list of users to whom it has responded. If you exit Outlook and then restart it, however, the list of the senders who have received automated replies is reset.
You might consider making the language in your alt text actionable, such as "Click here to download the ultimate content creation kit." Actionable alt text will essentially turn every linked image into another CTA. So, even if someone doesn't see the snazzy GIF of my latest offer (or if they hover their mouse over an image that does show up), the alt text will beckon them to click.
DISCLAIMER: We CANNOT determine or predict the results you will receive with your solo ad. It is your responsibility to have a high converting offer and sales funnel. We can guarantee that you’ll get at least the number of UNIQUE clicks that you paid for, delivered to the URL you’ve provided. There are NO REFUNDS after traffic has started and/or been delivered to you.

People buy when they feel that they have good reasons to do so. So, you need a strong value proposition (=great reasons for buying what you sell). If you don’t have it, you can’t be able to give people good reasons for buying. If you don’t know what—specifically—would make people see value in your offer, how could your email marketing (or any marketing) be effective?
"I have been using 10DollarSoloAds for several of my online businesses. Every time the customer service has been exceptional. They help me write ads, re-write ads I have written and make sure that everything is running smoothly. On top of that, I receive far better results from this solo ad company than I from any other that I have used. This is absolutely worth every penny."

That isn’t to say that sales-y promotions couldn’t ever create results—as marketing “gurus” have proved. The results just aren’t as good as they could be. Take the biggest gurus’ results—the ones they boast about—and calculate their conversion rates. Often their marketing is comparatively ineffective. They just have massive volume, so the sales numbers are impressive.
