Question 1

Why did my email say it was sent but never arrive?

Accepted Answer

Because "sent" means your mail left your device — it says **nothing** about whether it was accepted, delivered or seen. Several things can go wrong after that point, and each leaves a different trace.

**Where it can actually be:**

**In the recipient's spam or junk folder.** By far the most common answer, and the first thing to check by asking them.

**Quarantined by their organisation's mail filter**, where the recipient never sees it at all and it is not in their junk folder either. Corporate filtering quarantines messages silently, and only an administrator can release them.

**Still in your outbox**, if the send failed after being queued.

**Rejected by the receiving server**, generating a bounce message — which may itself have gone to your junk folder, which is a genuinely common compounding failure.

**Delivered to a different folder** by the recipient's rules.

**Sent to the wrong address**, particularly where autocomplete substituted a similar one — which is a frequent and invisible cause.

**Why messages get filtered:**

**Authentication failures.** If your domain's **SPF**, **DKIM** and **DMARC** records are missing or misconfigured, receiving servers cannot verify the mail genuinely came from your domain, and treat it accordingly. **This is the dominant cause for messages from business domains**, and is invisible to the sender.

**Sending from a new domain or address** with no reputation.

**Content triggers** — certain phrasing, excessive links, large images with little text, and attachments of particular types.

**Shared IP reputation**, where another sender on the same mail server has behaved badly.

**Attachment blocking** for executable and archive types, which many organisations strip silently.

**How to diagnose it:**

**Check your sent folder** — presence there means it left, absence means it never did.

**Look for a bounce**, including in junk.

**Ask the recipient to check junk and to ask their IT team about quarantine.**

**Send a plain, short test message** with no links or attachments, which isolates content from delivery.

**Check your domain's authentication records** if this recurs.

**Read receipts are unreliable** and easily declined.

Question 2

Why do my photos lose quality when I send them?

Accepted Answer

Because most messaging and social platforms recompress images on upload, and several also resize them — so what arrives is a smaller, more heavily compressed copy rather than the file you sent. What

Question 3

Why do my downloads keep failing partway through?

Accepted Answer

Repeated failures at different points suggest an unstable connection; failures at consistently the same point suggest something else entirely, and that distinction is the fastest way to narrow it. If

Question 4

Why has my phone suddenly started overheating and draining fast?

Accepted Answer

Because something is running continuously that should not be — and the sudden onset is the useful clue, since hardware degrades gradually while software problems appear overnight. The most common

Question 5

Why does my computer say a file is in use when nothing is open?

Accepted Answer

Because "in use" means a process holds a handle to the file, and plenty of processes do that without any visible window. What is usually holding it: A background indexing or search service reading

Question 6

What happens to your data when a subscription lapses?

Accepted Answer

It depends entirely on the service, and the answer sits in terms nobody reads — with outcomes ranging from full access retained in read-only form to deletion after a short grace period, which is why

Question 7

What should you actually do first if you think you have malware?

Accepted Answer

Disconnect from the network, then work through a sequence — because the instinct to start deleting things immediately can destroy evidence, spread the problem, or do nothing at all while the real
