Is there a application to take email addresses

can somebody tell me if there is a software to collect email addresses.

You need to give more details about what you want. If you want to gather subscribers in a mailing list, there are many ways to do that, but I prefer to go with 3rd party providers like MailChimp or CampaignMonitor for things like this.

thank you.

You can try these 3rd party software … MailChimp, Aweber or iContact.

i want to extract mailing addresses from any site.

Why do you want to do that, and why do you need software to help you?

If you are visiting a site and want to contact them, you should be able to find their e-mail address (if there is one displayed) quite easily.

If you mean that you want some kind of software that will search the internet and harvest e-mail addresses so that you can send spam e-mails to them, then forget it. We do not promote spamming or any similar technique in this forum.
