Marcus checks his phone at 6:15 every morning, before he is properly awake. Today there are sixty-three new emails. Two are from people he knows. One is from his daughter’s school. The other sixty are a furniture sale, a crypto tip, a warning that his “account will be suspended”, and fifty-seven things he cannot remember signing up for. He deletes them with his thumb, one flick at a time, and by the time he finds the school email he has already made sixty small decisions and had no coffee.
He has tried to stop it. He has unsubscribed. He has set up filters. He has marked things as spam so many times the button feels worn. The spam keeps coming, because each thing he tried fixes a different part of the problem, and none of them fixes the part that matters.
This is an honest ranking of the ways to stop spam emails, from the ones that help a little to the one that changes the question. Each section says what the method actually does, what it leaves open, and whether it can hurt you.
1. Marking as spam: trains a guess, one message at a time
Every major email service has a “Report spam” button, and pressing it teaches that service’s filter what you consider junk. It works, slowly, and only on mail that looks like mail you have already reported. The filter is a guess about the next message based on the last one, so a new sender with a new template starts with a clean record.
Google’s own help page describes the mechanism plainly: reporting a message as spam moves it to the Spam folder and helps Gmail learn which messages to send there in future. Note the word learn. The filter is catching up, and the people sending spam change templates faster than it can.
What it fixes: repeat mail from the same sender or the same style. What it leaves open: everything new, and the thirty seconds a day you spend feeding it.
2. Filters and rules: you become the sorting machine
Filters let you write rules: if the subject contains “sale”, archive it; if the sender is this address, delete it. Gmail, Outlook and Apple Mail all offer them, and a well-built set of rules can make an inbox look calm for a while.
A filter only acts on a pattern you have already seen and written down. That is the whole limit. You are doing the job of a spam filter by hand, and the job does not end. Every new sender is a new rule, every changed subject line is a rule that stops matching, and the calm inbox lasts exactly as long as you keep maintaining it. For the reader who wanted fewer decisions in the morning, filters move the decisions to the evening.
What it fixes: predictable mail from known senders. What it leaves open: the unknown, which is where spam comes from.
3. Unsubscribing: works for the honest, and it is a risk with the rest
Unsubscribing is the method most people reach for first, and it is the one people worry about most: can clicking unsubscribe be dangerous? The honest answer has two halves.
For a legitimate business, unsubscribing works. In the United States the CAN-SPAM Act requires commercial senders to include a working opt-out and to honour it within ten business days. A retailer you bought a lamp from three years ago will, in almost every case, stop when you ask.
For a spammer, the unsubscribe link is a different object. The Federal Trade Commission’s consumer guidance says it directly: do not reply to spam, and do not click “unsubscribe” in an unsolicited message, because doing so can confirm that your address is live and being read. At best you have told the sender you are real. At worst the link leads to a page built to collect a login or install something. The rule of thumb is simple: unsubscribe from companies you remember, and report the rest.
What it fixes: mail from real businesses you once dealt with. What it leaves open: everyone who was not going to honour the request, which is the mail that bothered you most.
4. Blocking a sender: closes one door of several thousand
Blocking sends a specific address’s mail straight to spam or the bin. It is satisfying and it is precise, and it does not scale. Spam rarely comes twice from the same address; the sender rotates through domains that cost almost nothing to register. Blocking works well on the one person you genuinely want to stop hearing from. Against bulk mail it is a game you cannot finish.
What it fixes: a named nuisance. What it leaves open: the next address, and the one after that.
5. Aliases and hide-my-email: the leak becomes traceable
This is where the methods start to change shape. Instead of cleaning up mail after it arrives, an alias changes what you hand out in the first place. Apple’s Hide My Email, part of its paid iCloud+ tier, generates a random address that forwards to your real one; if the alias starts receiving junk, you deactivate it and you know exactly which company leaked or sold it. Gmail’s plus-addressing does something similar at no cost, although the trick is well known and easy to strip.
Aliases are the first method on this list that treats the address itself as the thing to protect. The limit is that an alias still forwards everything sent to it. It tells you who leaked; it does not stop the leaking company’s partners from writing before you notice.
What it fixes: knowing where the spam came from, and being able to shut that source. What it leaves open: the main address you already gave to two hundred places over fifteen years.
6. Opt-in: change who is allowed in, not what you do with what arrives
Every method above shares one assumption: anyone who has your address can put a message in front of you, and your job is to deal with it afterwards. Standard email was designed that way in the 1980s, and every filter, rule and block is a patch on that design.
Opt-in email flips the assumption. You approve the people and companies you want to hear from, and mail from anyone else does not land in your Inbox. This is what people are searching for when they type “opt in spam”: a setup where the default is closed and you open it, one sender at a time, instead of the default being open and you closing it, one sender at a time, for years.
That is the mechanism behind OptMsg, and it is worth being precise about what it does. Only people you approve can reach your Inbox. Everyone else goes to Trash, where the message is kept for thirty days so you can approve a sender you actually wanted, and then deleted automatically. You are not building filters and you are not guessing; you are answering one question, “do I want to hear from this sender?”, once, and the answer sticks. It uses patent-pending opt-in technology to do the sorting at the door instead of in the room. If you want to see what a morning looks like when the decisions waiting in your Inbox are ones you already made, you can create your account and forward your existing mail to it.
What it fixes: the shape of the problem. What it leaves open: you still choose who gets in, which is the part that was supposed to be yours.
The honest ranking
If you are staying with the inbox you have: report spam rather than unsubscribing from anything you do not recognise, unsubscribe only from businesses you remember, use filters for the predictable senders, and start handing out aliases instead of your real address. That combination will make Marcus’s sixty-three emails into perhaps forty, and it will cost him ten minutes a week to keep it there. If you are weighing a cleanup app instead, we compared the main ones and they land in the same place.
If you want the sixty to stop being your problem, the answer is not a better version of any of those. It is an inbox where arrival is something you approve. That is what OptMsg is built to be, and the door is open at optmsg.com/signup.

Frequently asked questions
What is the best way to stop spam emails? It depends on what you are willing to keep doing. Reporting spam and filtering both work but need ongoing effort. Unsubscribing works for legitimate businesses only. Aliases protect the address you hand out. Opt-in email, where only people you approve can reach your Inbox and everyone else goes to Trash, is the one approach that changes the default instead of cleaning up after it.
Can clicking unsubscribe be dangerous? It can be, in unsolicited mail. The FTC advises against clicking unsubscribe in spam because it can confirm your address is active, and the link may lead to a page designed to steal a login. Unsubscribe from companies you remember dealing with; report the rest as spam.
Why do I still get spam after unsubscribing? Legitimate senders are required to honour an opt-out, but spammers are not sending legitimately in the first place, and a single address is often sold on to other lists. Unsubscribing from one list does not remove you from the copies.
Do spam filters actually work? Yes, on mail that resembles mail already reported. Filters learn from what you and other users flag, so a sender using a fresh template or a new domain often gets through until enough people report it.
What does “opt in” mean for email? An opt-in inbox is one where you approve senders before their mail lands in your Inbox. On OptMsg, only people you approve can reach your Inbox. Everyone else goes to Trash, kept for thirty days in case you want to approve them after all.
