Email list management

What's the best email list for your business or organization? A permission-based one. That means everyone on it said it's okay for you to contact them. It's better than an email list you buy or rent, because you already know the people on your email list want to hear from you and are interested in you. It doesn't cost you anything to build one. Email Marketing helps you start your email list — and keep it growing, too.

Start and grow your email lists
    * Add our Join My Mailing List button to your website and your Facebook profile or fan page to collect visitors' email addresses
    * Use our sign-up form or guest book to collect email addresses at your place of business
    * Add our Forward-to-a-Friend link in your email campaigns or on your Facebook page to reach new people
    * Our SafeSubscribeTM and SafeUnsubscribeTM features increase new signups. Contacts can easily unsubscribe if they change their minds.
Import your existing email lists
    * Type or copy and paste your email addresses into your Constant Contact database
    * Easily import your permission-based file: Excel (.xls), comma separated value (.csv), or text (.txt)
    * Import effortlessly from Google/Gmail contacts, Microsoft Outlook®, Outlook Express®, QuickBooks® by Intuit, Salesforce.com or ACT!® by Sage®
    * Add contacts from wherever you are — from your PC or Mac, Facebook, or using QuickView on your iPhone or iPod Touch

Group your contacts into targeted email lists for powerful results
    * Segment based on interest or shared characteristics like location or birth month
    * Combine multiple email lists into a new, single email list when you need one big mailing. We'll make sure people on multiple lists only get one message
    * Sort your contact lists to segment and browse contacts more easily.

Keep your email list up-to-date and reliable
    * Access and update your contact database from any computer, anytime
    * Our SafeUnsubscribe form asks contacts why they leave, so you can make changes to improve retention
    * Let contacts choose which email communications they want to receive
