What Is PayPal?
Your customer clicks "Buy Now" on your site, and moments later you see the money in your account. No card numbers to store, no PCI compliance to wrestle with. That’s PayPal, a digital payment platform that lets businesses accept credit cards, debit cards, and PayPal balances without building a payment system from scratch.
But here’s why you’re reading this article: your TechSpy scan flagged something about PayPal. It might have found a PayPal script tag on your site, or—more likely—a DNS record pointing to PayPal’s servers. That’s not an error. When you set up PayPal to send branded emails (like payment confirmations that look like they come from you) or to verify domain ownership, you add small text records to your domain’s configuration. Those records are what TechSpy noticed.
PayPal isn’t just a payment processor; it also sends emails on your behalf—things like receipts, shipping updates, or dispute notifications. To make sure those emails are trusted by inboxes, your domain uses email authentication records that explicitly trust PayPal. Think of it like giving a courier service an approved ID badge so the front desk knows they really work for you.
How PayPal Works with Your Domain
Layer 1 — What actually happens
Imagine a customer pays through your online store. PayPal takes over the payment screen, processes the transaction, and then sends the customer an email that says “thanks for your order from [your company].” For that email to land in the inbox—not spam—the email providers (Gmail, Yahoo, etc.) need to check that it really came from your domain. Your domain vouches for PayPal by publishing a short guest list of who’s allowed to send mail. When the email arrives, the provider checks that guest list, finds PayPal on it, and lets the message through. If the list is missing or wrong, the email looks forged and gets blocked.
That “guest list” is a set of tiny rules stored in your DNS (the internet’s phonebook). One rule says “PayPal’s mail servers are allowed to send email for my domain.” Another provides a cryptographic seal that proves the email hasn’t been tampered with. All of this happens in milliseconds, invisible to you and your customer.
Why It Matters for Your Business
When the DNS records are right, every payment confirmation and shipping notice arrives in your customer’s inbox looking just like your other emails. That builds trust and cuts down on “where’s my receipt?” support tickets. It also meets the requirements of Google and Yahoo’s stricter email rules—without proper authentication, bulk emails get rejected outright.
If the records are missing or misconfigured, PayPal’s emails can end up in spam, or worse, be blocked entirely. Customers might think they were scammed because the payment went through but the confirmation never appeared. Worse, an attacker could exploit missing verification to impersonate your business on PayPal, directing payouts to their account.
This matters for everyone who touches customer communication: marketing teams sending out order follow-ups, support teams handling payment disputes, and even executives whose reputation rides on every transaction. You don’t need to be technical—you just need to know the configuration exists and that it needs to be kept healthy.
Common Issues and Warning Signs
Your first clue is often a customer complaint: “I paid but never got a receipt.” Or you notice that PayPal emails to your own test accounts land in the spam folder. TechSpy may surface warnings about incomplete SPF records or a missing DKIM selector for .

How to Fix or Improve PayPal’s DNS Setup
Most of these steps take less than five minutes if you have access to your domain’s DNS control panel (wherever you bought the domain or host your website). If someone else manages your DNS—an IT person, an agency, or a hosting provider—forward them this list and ask them to check each point.
Once these records are in place, PayPal’s emails will be properly authenticated, and your customers will get the receipts they expect.
