I am developing a software but for that I want to know as if i send an email then how can i check the sent email is in recipient's inbox/ Junk.
I am using AsP.net and c# technology for this
Please reply
You can't detect what is done with the email once it is delivered to the users inbox other than requesting a delivery receipt and a read receipt but the user can opt out of these.
The best way to avoid being marked as spam is to use a trusted third party service such as Campaign Monitor or MailChimp.
Failing that you should make sure that your email has a proper from address set, that you have set up SPF records to allow the sending IP official permission to send email on behalf of the from domain, keep your html to content ratio reasonable and if possible use an email address that your customers have already received an email from before so that there is a higher chance that the address is already in a whitelist.
You really can't because there are many different email spam solutions out there and they don't send a status back saying whether they delivered the email to the recipient or not. What you can do is send an email with a tracker to see if the receiver opened it.

I am new to firebase and I am trying to handle firebase user authentication in React.js. I did manage to create users with email and passwords. But, now I would like to send the user an Email link to reset their password.
My code currently look like this.
// This line of code belongs to the top
import { auth } from '../firebaseConfig'
//This part goes under the React component
<p onClick={async () => {
try{
await sendPasswordResetEmail(auth, // My Email Id)
alert('Password reset link has been sent to your email')
}
catch(err){
alert(err)
}
}}
>Forgot your Password ?</p>
However, I do not get any error messages and I do get the alert message that says "Password reset link has been sent to your email." Unfortunately, I didn't receive any email. Note that I have given my own email id as the parameter for testing purposes.

Did you check your spam folder? We recently see a lot of the emails from Firebase Authentication ending up in the user's spam folder or being marked as spam in a system along the way. This is being tracked in this status message on the Firebase dashboard and in public issue #253291461.
To reduce the chances of the messages getting marked as spam, consider taking more control of the email delivery yourself.
As a first step, consider using a custom domain with your project. Email that comes from a custom domain has less chance of being marked as span.
As a second step, consider setting up your own SMTP server.) for delivering the email, so that the emails are not being delivered from Firebase's shared infrastructure anymore.
While these steps are more involved, they typically will drastically reduce the cases where the messages from Firebase Authentication are marked as spam.
Full Guide Based on Frank's Answer
Firstly create a new email account you can use to relay the Firebase emails through the SMTP server with. I personally chose Gmail, but I tested with Outlook and it also works.
You can now find an SMTP server host that will work for your scenario. If you're sending less than 1000 emails per month you can find free and reliable hosts. I chose SMTP2GO's free option.
Now you've found the SMTP host, add the email address you've chosen as a single sender email (note that if you do own a domain, you can alternatively use that to send emails).
Note that you will have to verify the email, usually by your host sending a link to the email's inbox. Make sure to check spam.
Once verified, navigate to where you host allows you to add SMTP Users and add a new user. This will allocate an SMTP username and password.
Navigate to the Firebase console, and choose the Authentication option from the sidebar (within the Build product category).
Go to Templates → SMTP Settings and enter the details of your SMTP server. The username and password fields are to be filled with the SMTP user login you created in the step above.
It is better to use TLS, but I believe SSL should work too but it is untested.
Click save, and you're all set up - but there may still be steps to perform depending on your email provider.
Provider Specific Steps
If the emails are being sent to an account managed by Google you will have no issues with your emails being quarantined by anti-spam policies and it will work immediately.
If you are using Outlook, you will have a different problem on your hands. Outlook's built in defender will most likely have auto-quarantined your email under multiple policies - that bit is important.
These policies are likely to be both spam and phish policies. If you unblock one of them, the other will catch it and re-quarantine.
Unblock both policies for the email address, and test. You can see the status of quarantined messages in Microsoft 365 Defender app under Review → Quarantine. Please note that you will need to be an administrator to add global allow policies to your email accounts.
If this still doesn't work it is likely that your company has an additional external filter (as mine did), and you will have to add the IP's manually to the Tenant Allow/Block Lists spoofed senders tab.
I've recently found out that, if Evernote's user does not verify his email address, all requests to Evernote API is not working. But I didn't find any ways to request email verification in Evernote's web interface, looks like the proposal to verify email appears randomly ? Are there any ways to request email verification from the user ?
You can ask users to change their email address via the page on the web, which will send them a verification email and verify their address.
i 'm .net developer. i just have a task to make newsletter application that can send emails to subscribers. here i just want that each mail goes to mail account inbox not in spam. Is there way to make my email have higher priority and they all goes to inbox section.
In short my all emails goes to inbox folder of all subscribers mail address.
I know google have detection algorithms to put email to inbox section or spam section. here my company gives me instruction that all mail goes to inbox folder.
Is there possible with programming to send them.
please help me......
In short no, since major email server check for reputation of IP from which mail is being sent. That said check for the reputation of your mail server #http://multirbl.valli.org/ or any other, if you find that (and you will probably find) that it is black listed forward that report to your higher authority citing that the IP is blacklisted for sending mail.
If the IP is not blacklisted then you must be using spam triggering words in the mail.
Since you have said In short my all emails goes to inbox folder of all subscribers mail address. then your IP is not blacklisted and will go to Inbox, irrespective weather they are subscribed or not.
Email is sent using Amazon simple Email service form my website. When an email is sent to any Yahoo or Gmail address, it is delivered to Inbox; but when it is sent to Hotmail,it is delivered to Junk.
Why only Hotmail Treats my email as junk?
When an external user sends email messages to an Outlook.com account,
SmartScreen® filter technology evaluates the content of the messages
and assigns each message a rating based on the probability that it is
a junk email. This rating is stored as a message property called a
spam confidence level (SCL) within the message itself. The SCL rating
stays with the message as it is sent to other anti-spam protection
layers within Outlook.com. Rules inside Outlook.com are set to handle
email messages with various SCL ratings. If a message has an SCL
rating lower than a certain threshold, it is considered to be spam,
and a rule then deletes the message rather than sending it to the
user's junk email folder. If the message has a higher SCL rating than
the threshold, the email is delivered to the user's junk email folder
rather than to the inbox.

Not all the Anti-Spam system depends only on 3rd party blacklists. Major email service providers builds their own reputation table in addition with the use of major 3rd party blacklists like spamhaus, barracuda etc. In your case, you are using Amazon SES to send mails.
I, myself found enormous marketing mails coming from Amazon SES. If the reputation of your email service provider is bad in hotmail then it may trigger the suspicious level of your mail regardless of your email service provider reputation at other blacklist providers. In addition to this, if your subject, body content contains some suspicious words then your mail will end up in junk folder.
Most emails sent from third party applications such as Wordpress, Joomla, or Amazon get diverted to junk and sometimes they fail and get stuck behind a security layer. I know for a fact with Wordpress Contact Form 7, this is the case many times.
After so many years and finally attending a seminar for this particular issue, I finally was able to solve this problem specifically for Hotmail (Outlook.com).
Before you do anything ensure your SMTP settings in your web config file (ASP.NET) are written correctly or in case of plugins (Wordpress) make sure the fields are filled correctly. This means ensuring these are the settings you are using for Outlook:
From: your email ("asdf#outlook.com")
From Name: "Your name or company name"
Host: smtp.live.com
Type of Encryption: TLS
SMTP Port: 587
SMTP Authentication: Yes
Username: Same you use to login (usually the complete email address)
Password: Enough said there
IMPORTANT - Send a test email even if it fails. The point is to trigger an activity in Outlook and have them flag it as an
unauthorized connection
Now, to the fix:
Go to Outlook.com
Login
go to Account Settings
Choose Security & Privacy
Click on "See my recent activity"
The most recent activity should be the fail attempt. Authorize it as a trusted connection.
Done!
Re-test and you shall see your emails showing in the inbox as an authorized connection. Doing these steps let Outlook know that your emails from Amazon are legitimate connections and not Amazon trying to spam your account with solicitations etc.
Mostly it is a email service provider specific thing but you can do below checks
Ensure valid sender email address
Try not to use keywords like gift, prize etc. which are preferably spam activities

I have my little web application, with simple registration strategy - provide email and password and you are done.
Recently bot's starting to attack my application, registering big number of users from non existent emails using the same passwords.
I want to prevent that. My idea is to extend login verification, but check the existance of email address. Do you know any web services (prefereably WCF) that could do that?
This is definitely not the way to solve this problem. Try one of these
Allow user to enter only username and send auto-generated password to their email.
Send a verification link to the user email and approve him/her only after verification
This has been discussed on How to check if an email address exists without sending an email? . Basically there are ways verify email addresses, but in practice none of them is reliable. However, you can still check via SMTP, and if the server denies the existence of the expected user, send him an email with a verification link anyway. This does not prevent spammers from setting up fake servers that acknowledge the existence of any user, of using other peoples email addresses, but it's probably the closest you can get to your initial requirement of having no verification email.
I would recommend you to update your registration form. Try to use something tricky for bots. For example, post the form via AJAX with JSON object wrapper.
Try a service like: http://elasticemail.com/
You can use the api to check if the email was delivered. There is also a 'bouce list' you can check.
