Is It Better to Unsubscribe or Mark as Spam? What 16 Email Experts Say

Flag Impersonation Attempts as Spam

When I receive an email that appears to be from someone I know but shows signs of impersonation (such as unusual requests or uncharacteristic phraseology), I always mark it as spam rather than simply deleting it.

Whether the person's email has been hacked or the fraudsters have spoofed the address, either way, they don't have good intentions. I have known this to happen within our business, where a colleague's email address was cloned, and they were asking the recipient for bank details. If a strange request comes from someone, we should just give them a quick call to check if it is legitimate. If not, then it's probably a phishing attempt, and it should be flagged as spam.

Identify and Report Manipulative Emails

I mark an email as spam when it crosses the line from annoying to manipulative. If it pretends we've talked before, fakes urgency, or hides the opt-out like it's a secret mission - that's 100% spam.

Delete is for stuff I don't care about. Unsubscribe is for senders I once cared about. But spam is for the ones who don't play fair - and they don't get a second chance.

Train Inbox Filters with Spam Reports

Flagging an email as spam sends a message. It instructs your inbox to filter out similar messages in the future. That's better than deleting or unsubscribing. Deleting is a momentary solution. Unsubscribing is only effective when the sender is legitimate. When the source doesn't feel right, spam is the way to go.

Unsubscribing is sensible when the sender is familiar and trusted, but the message is no longer relevant. Spam is for anything phony, coerced, or inappropriate. Trust your instincts. Mark it and proceed.

Use Spam Button for Suspicious Senders

I mark emails as spam when they are just that: spam. This helps train my email junk filter to understand what is spam and what is not. If I have subscribed to something or bought something somewhere and they send me email, I unsubscribe. I only use "delete" for legitimate email that I want to keep getting. When you hit "delete," it signals to your email filters that the email was legitimate and you are happy to continue getting those types of email.

Block Malicious Emails with Spam Filter

Generally, when you mark an email as spam, it moves into a spam folder where it eventually gets deleted. You may not want to risk opening the email to unsubscribe because a link to unsubscribe could allow access to a virus or other malware. Marking an email as spam also usually means that the sender will be blocked from sending more emails, or future emails from the sender will be automatically marked as spam.

Report Persistent Unwanted Marketing Messages

Running an SEO agency, I get flooded with emails from people pitching backlinks. Most of the time, I'll just delete the message or hit unsubscribe. The only time I actually mark something as spam is when I've already replied and told them I'm not interested, but they keep pushing anyway, sometimes multiple times a day. If you can't take no for an answer, that's when it crosses the line from outreach to straight-up spam.

Protect Inbox from Deceptive Senders

The quickest way to get flagged as spam is by spoofing sender familiarity. I recently received an email that appeared to be from a CI/CD provider we use, but it was actually a marketing campaign with a spoofed subject line. That one got flagged immediately.

I delete marketing emails every day, but spam is reported when someone deliberately conceals their intent. If you are honest about what you are offering, I may read it. However, if you attempt to deceive me into opening it, I will ensure you never make it to my inbox again.

Combat Misleading Emails with Spam Reports

One key reason I mark an email as spam instead of just deleting or unsubscribing is when the email feels deceptive or comes from an untrustworthy source:

• The sender fakes familiarity ("Just following up!" when I've never interacted with them)
• There's no clear unsubscribe link
• The domain looks suspicious or mismatched
• It was sent to an email address scraped without consent

In such cases, marking it as spam not only protects me but also helps email providers improve their filters. I reserve unsubscribing for legitimate marketers who may have just missed the mark in relevance.

Safeguard Your Inbox from Irrelevant Pitches

When I mark something as spam, it is because the sender skipped basic context and blasted us with something completely irrelevant or aggressively misleading. The line between delete and spam gets crossed when someone sends back-to-back emails using fear tactics. These emails signal poor training and desperate tactics. They go straight into the spam folder.

Mark Unethical Outreach as Spam

I mark emails as spam when they pretend to know me - but clearly don't. If a message opens with fake familiarity or misrepresents how they got my contact information, that's an instant spam flag. Deleting or unsubscribing is for irrelevant but honest outreach. If someone is using manipulative tactics or scraping without consent, I mark it as spam to train filters and protect my inbox going forward.

Penalize Poor Email Acquisition Practices

My response to poor email list management and shady email acquisition practices is to label the email as spam. When I receive an email newsletter from a legitimate company that I am certain I never subscribed to, I do not simply delete it or unsubscribe. I send a stronger message by marking it as spam. This action may influence the reputation of their email service provider and negatively impact their subsequent email delivery.

Efficiently Manage Inbox with Spam Button

I use the spam button to mark emails that I am aware of as unwanted or sneaking into my inbox. It is a fast and efficient method that can help me maintain a tidy inbox. As time progresses, my email provider becomes familiar with what I do not want, so it actually filters out similar emails. It is quicker than unsubscribing, not to mention more dependable.

Thwart Sneaky Unsubscribe Avoidance Tactics

Instead of hitting the delete button or the unsubscribe link, I often simply mark an email as spam instead, if I feel the sender is trying to be sneaky and avoid me successfully unsubscribing. For example, when I unsubscribe, only to see the same type of email come from a different person with a different subject line. When I mark them as spam, I can help the system learn and avoid similar content from other senders.

Enhance Email Filtering by Reporting Spam

The decision to mark an email as spam instead of simply deleting it or unsubscribing is usually made out of the necessity to ensure that my inbox will not be disturbed in the future. When I unsubscribe from a mailing list, there is always a possibility that the email address will be sold or shared. Reporting it as spam will allow my inbox to learn with time, becoming more intelligent about what is a legitimate email and what is not.

Counter Manipulative Unsubscribe Processes

When I mark an email as spam, it is because the sender was clearly attempting to engage in manipulative tactics that made it difficult to unsubscribe or otherwise prevent future emails. Some cases involve unsubscribe links buried in the fine print or within a winding series of steps that are tiresome to follow. By marking emails as spam, I avoid wasting time dealing with inefficient unsubscribing processes.

Flag Emails with Broken Personalization Tokens

If an email starts with something such as "Hi [First_Name]" or has broken formatting tokens which obviously should have auto-filled but did not, those are examples of what I mark as spam mail. If a sender cannot get a name right or leaves placeholders visible, I do not want them to have access to my inbox or data. By flagging them, you teach the filters to recognize what should be blocked.

Report Deceptive Subject Lines as Spam

When a subject line blatantly lies or attempts to manipulate with false urgency, I mark it as spam immediately because it signals dishonesty from the outset. I recall receiving an email with the subject line "Payment failed on your last order," which upon opening was merely a generic cold pitch for a financial tool I had never heard of. Reporting it as spam was the only sensible solution.

Mark Fraudulent Prize Offers as Spam

When I get an email giving me a bogus prize, I do not just erase the mail but I mark it as spam. Such emails are meant to entice me by offering some substantial prize or financial gain, and thus by getting my personal information or selling it to other entities. Marking the email as spam means my inbox will remain safe and the email provider will learn to filter similar emails in the future.
