TempMail.now vs Guerrilla Mail
Guerrilla Mail has been around for a long time, and it does one thing most temp mail tools skip: it lets you send. TempMail.now takes a different path, with private addresses and a timer you set. Both are free and need no account. This page lays out the differences in plain words so you can choose in a minute.
Guerrilla Mail lets you send email and keeps messages for about an hour, but it uses a fixed public inbox model, so anyone with the address can read it. TempMail.now is receive-only, but gives you a private random address, a timer from 5 to 30 minutes, attachments, and auto-delete. Need to send? Pick Guerrilla Mail. Need privacy and cleanup? Pick TempMail.now.

The table shows two different designs, not one good tool and one bad one. Guerrilla Mail trades privacy for the power to send. TempMail.now trades sending for a private inbox that cleans itself up.
Sending: the big Guerrilla Mail advantage
Most temp mail tools only receive. Guerrilla Mail also lets you write and send a message from the throwaway address. That is useful when a site wants you to reply to confirm, or when you need to send a one-off note without using your real name.
TempMail.now does not send. It is built to catch codes, links, receipts, and files, and to get rid of them on a timer. If sending is on your list, this row alone may decide it for you.
Public vs private inbox
This is the other big difference. Guerrilla Mail uses a fixed public inbox model. Anyone who types the same address into the site can see the same messages. That is fine for a newsletter you do not care about. It is not fine for a password reset or a link that logs you in.
TempMail.now gives every visitor a random address that no one else is handed. When your timer ends, the inbox and its messages are deleted. You can also press Change Email at any time to rotate to a fresh address on another domain. For the full picture, read is temp mail safe.
Inbox lifetime
Guerrilla Mail keeps each message for about an hour, then drops it. Check their site for the current rule. That window is long enough for most slow replies.
TempMail.now lets you choose the window before you start: 5, 10, 15, 20, 25, or 30 minutes. A quick 10-minute mail timer covers a code. Thirty minutes covers a long form. When time is up, everything is gone. You do not have to remember to clean up.
Attachments, languages, and mobile
Both tools receive attachments. On TempMail.now a PDF or image opens right in the inbox. For Guerrilla Mail, check their site for the current size limit.
