How to retrieve email address after the recipient click on a button inside email - email

I am working on a web apps with Asp.Net (C#) and I have a problem like this:
I will sent out an email for more than one person and there is a link in the email. If user click on the link I want to retrieve the email address of the respondent (as query string or whatever).
Is it possible?
How should I do?
Thanks in advance.

If you generate the emails dynamically, you can add a token to the url that is unique to each email address you send to. Your landing page will use the tokens to register a hit to a database.
On another note, please remember to handle information like email addresses with great care (i.e. securely), for example when storing them in a database.

API to fetch the contacts from domain email address

I have get the contacts from gmail,hotmail and yahoo email providers.
And i want to get contacts from any domain email addresss which users enter in a textbox. Is it feasible?
For example,
Here we can see the hotmail contact import: https://techjoomla.com/invitex/how-to-use-hotmailrest-api-to-import-contacts.html
Same way i want to import contacts from a domain email. i.e say if i have this email address test#stackoverflow.com and having few contacts.
Using PHP, i want to fetch the contacts from test#stackoverflow.com
Hope the above provided detailed explaination.
So, what you want is possible if that mail server allows you to access the contacts you have there. But, I am pretty sure that you will definitely not be allowed to fetch contacts from every single mail server you want. But, I would suggest you to give that try before losing hope.

Adding new contact using mailgun in rails

I am trying to build app where users can subscribe for new updates.
My mailer is configurated with mailgun. Everything works fine except when I try to add new user with this method (as in official document): http://documentation.mailgun.com/user_manual.html#mailing-lists.
Honestly I have no idea how to send email adress from form directly to add_list_member(mail) without saving it to my database.
I will be grateful for any help!
Create two fields in your form
Name
Email
On Form's submission you send the input from the user to your backend for processing.
The backend takes the form's input, makes a few check to ensure the email is correct and not mispelled.
If the above is successful your backend pushes the email address and name to a mailing list, for reference that's something which you can create with the API or from the control panel (https://www.mailgun.com/cp/lists?domain=YOURDOMAIN.COM)
Then you just email the address provided in the email list

How to detect multiple registration to the web from a single user

use php and mysql,
My situation: users register to the web by entering username, email, password , birthday, sex and then activate account by clicking the link in their mails. Email and password are used in the log-in process.In database,I also record IP address and date-time of registration.
The problem is some users registered too much accounts to do something on the web as I limited one account per one click. The easy way is to check their IP address is existed or not, but in some academy organisation or company use the same IP address for all computers.
How to limit their registration and not to effect everyone who are those in the same ip address?
Think of a way to block automatic registration. That's usually why you see the many registrations pattern. Robots crawl and register any site they find and can figure out.
I usually encode the FORM and use JS document.write() to print the form. Or use a hidden field filled by JS using and external obfuscated file. Or a CAPTCHA...
See if this does not fix your problem...

Custom email form in iPhone app?

Say I want to send email to my server, but I want the user to not see my address, or perhaps I want the subject to be preset. What if I want to email the value of a UISlider or other UI element without the user seeing the whole email view. How can I do that?
Must I use an Apple class, or can I use my own UITextFields?
The benefit of the Apple class is that you get the email address of the user. If you do not care about that, you can submit anything you want to your own server as POST data or by whatever means you wish. The interface can look like mail but the functionality will be like a web form.
If you need the address of the user and do not want to ask for it, then you will have to reveal the destination email address. You can specify a subject and body, but the user will be able to modify it.

tracing mouse clicks on website

I am new to website designing and wanted to know couple of things.
when some clicks on the link on my website say www.google.com, can i trace that how many people clicked on it.
When i send out emails with attachments, can i record how many people opened those attachements. btw this is not yahoo or gmail, its my personal email with an ISP.
if so, please put references so i can read them or explanation if possible
Create the links on your website so that they do a GET to your website first, and then redirect to the desired website.

The email attachment is a different problem. If you send an email that reads the attachment from your website, you can record the traffic.
For tracking outbound clicks, services like Google Analytics can wrap every link on your site with JavaScript and provide statistics and sexy graphs.
For tracking email attachments, it depends on the attachment. Static files like images can't make callbacks to the Internet, but something like a PDF with embedded JavaScript might be able to.
As for links within the emails, you can make each link in each email unique by associating a token with each email recipient, e.g. Some Link. Store the token in a database along with the recipient's email address and later you can cross-reference hits on your site with emails you sent out.
I know there are a handful services that do the latter, but I can't name any offhand. Search for "email newsletter service."
