# Situations

- [A customer says they never got your email.](https://www.emcheq.com/situations/customer-says-they-never-got-your-email): Before you assume it's spam filtering or they're lying, check the obvious thing first: the address might not exist. Here's how, without sending another email.
- [Someone is sending emails pretending to be your company.](https://www.emcheq.com/situations/someone-is-spoofing-your-email-domain): Your account probably wasn't hacked. Someone is forging your domain in the From address. Here's what's actually happening and how to shut it down.
- [Tired of fake signups, trial abuse, or bogus orders?](https://www.emcheq.com/situations/stop-fake-signups-and-fake-orders): Disposable addresses, typo domains and throwaway inboxes drive most fake signups, trial abuse and card-testing orders. Catch them at the point of entry, honestly, without overpromising.
- [Find out who'd click, before someone outside your company does.](https://www.emcheq.com/situations/phishing-test-for-small-teams): Enterprise phishing-simulation platforms are priced and sized for enterprises. Small teams get targeted too - here's a way to test and train without an enterprise sales process.
- [Suspicious orders piling up in your store?](https://www.emcheq.com/situations/fake-orders-at-checkout): A spike in orders with a fake or disposable email address is one of the fastest signals of card testing or fraud. Check it before you ship, not after the chargeback.
- [Something feels off about this applicant's email.](https://www.emcheq.com/situations/is-this-candidates-email-real): A free webmail address, a domain that doesn't quite match the company, or an address that doesn't even exist - all worth 10 seconds before you schedule a call.
- [One client's bad list just put every client's domain at risk.](https://www.emcheq.com/situations/protecting-client-domains-as-an-agency): Shared sending infrastructure means one client's dirty list or unauthenticated domain can drag down deliverability for everyone else on the account. Here's how to isolate and monitor it.
