Should you use a separate email address for shopping?
For many people, yes.
Shopping email has a habit of growing.
A store asks for your address to send a receipt. A restaurant offers a coupon. A retailer wants you to create an account before checkout. A loyalty program requires email before it will give you the discount.
Each signup seems small.
Over time, those messages become a meaningful share of an everyday inbox.
A separate email address creates a boundary between messages you chose to receive for practical reasons and the inbox you use for family, work, bills, travel, or anything else you actually watch closely.
The simplest option: another free email account
Creating a second email account works.
It gives shopping email somewhere else to go and costs nothing.
For many people, that is enough.
The tradeoff is that you now maintain another full email account. It has its own login, settings, storage, recovery options, spam folder, and all of the other features that come with a real mailbox.
If that does not bother you, there is no need to make the problem more complicated.
Another option: email aliases
An alias gives a company a different address while forwarding the message somewhere else.
Aliases can be useful for privacy and organization.
But forwarding does not solve every version of the problem.
If your goal is simply to keep retailer marketing out of your everyday inbox, forwarding the retailer's mail into that inbox still leaves you managing the resulting messages.
Temporary email
Temporary addresses can be useful for something you truly need once.
The weakness appears later.
A retailer may send another verification message six months from now. A website may require the same email address for account recovery. A loyalty program may still associate that address with your account.
If the temporary mailbox is gone, the old address is no longer very useful.
A permanent junk inbox
The fourth option is a steady email address whose entire job is receiving low-sensitivity signup email.
That is the model behind SpamCatcher.
Your username stays yours; receiving requires an active paid subscription. Old messages expire after 30 days.
You can give the same address to stores, restaurants, loyalty programs, and other noisy signups, then check that inbox only when you actually need something.
It is less sophisticated than an alias system.
That is intentional.
Sometimes the shopping email matters
A commercial relationship can generate both marketing and useful records. A retailer may send a receipt. A repair company may send an invoice. A store may send return instructions or warranty information.
That does not necessarily mean the whole relationship belongs in your primary inbox. A separate shopping inbox can keep it contained while letting you save the occasional message or document that matters.
With SpamCatcher, messages expire after 30 days. Before then, you can send an individual sanitized copy to your verified account email or download a supported scanned PDF. Forwarded copies omit images. Keep important records somewhere permanent, and use a full mailbox if you need replies or long-term storage.

Which option should you choose?
Use your normal email if you do not mind the extra messages.
Create another free mailbox if you want complete separation and do not mind managing a second account.
Use aliases if you care about giving different addresses to different services while still receiving them elsewhere.
Use a dedicated junk inbox if you want one steady address for the category of email you never wanted mixed into your everyday inbox.
There is no universally correct answer.
The useful part is making the boundary deliberately instead of letting every signup choose your inbox for you.
If a dedicated signup inbox sounds simpler, SpamCatcher is $9/year.
