Having a huge prospect email(or phone number) list is a much-needed resource for some small businesses in the early days of their business, because:
1) they can help businesses develop email marketing campaigns.
2) businesses can provide information about new products to them directly.
3) the cost of marketing is low (compared to advertising and social marketing).
4) it is the primary drivers of traffic to website.

There are many ways to help you get a list of potential emails, such as from web pages (Contact Form or About us page), search engines (google, Firefox, bing), social networking sites (instagram, LinkedIn, Facebook, Twitter), and email services (gmail, outlook, yahoo). Of these methods I value the most is to get the email list from Instagram.

There are two reasons:
First, a large number of users are using Instagram and it has been growing.
Instagram was launched in 2010 and since then has seen exponential growth. It has more than 700 million active users and over 8 million registered business accounts. Business accounts usually contain email information and telephone numbers. You can collect email addresses and phone numbers for marketing purposes, to get sales leads or to get a pool of people interested in your competitors’ brands.

Second, you can get a clear targeted email list.
Unlike the purposeless scraping of webmails, on Instagram, you can acquire a group of interested customers through your competitors' followers or trending hashtag. First get the follower list of competitors or trending hashtags you suspect may be your potential customers, then get their contact details from their profile. If your product content is reliable, these people may be the source of your first pot of gold.

Obtaining millions of emails manually can cost you a lot of time and effort, luckily you can use an Instagram email scraper tool.
