Expanding a business contact database: Top-4 tools to find an email address in 2021

When discussing email marketing, the need for an email parser is beyond question. In addition to providing a reliable list of legitimate email addresses, an email finder also saves a lot of time and effort that would have gone into manually looking up addresses.

In this article, we will discuss the main advantages and disadvantages of email collection software, as well as share the 4 best tools that marketers and sales professionals love to use for successful lead generation.

Main advantages and disadvantages of programs for finding email addresses

From the positive aspects of using email hunters, 5 points can be distinguished. We can immediately say that there are more good things than bad.

  1. A quick way to find contacts.
  2. Ability to specify several sites from which the program will retrieve contacts.
  3. The collected data can be automatically sorted and structured in any convenient format (for example, CSV, Google Sheets, TXT).
  4. The platforms provide a bulk search for email addresses by keywords, countries, and other categories.
  5. Some tools have in-built email verifiers.

But no software is without flaws. Be sure to take them into account before using the tools that we have listed for you below.

  • Often, antispam services or email providers place trap addresses on websites to prevent bulk parsing and purchasing of email address databases. If there is even one such address in your database, your campaign can get into spam.
  • Since the addressee did not consent to your campaigns, there is a possibility that they will mark them as spam, will not open it, or will delete it. Whenever a user sends your email to spam, the percentage of complaints about it becomes higher. And if this percentage is high enough, your account can get suspended. For example, in CampaignMonitor’s case, this rate is 0.5%.
  • If you end up with a mailing list for several thousand recipients and send the same emails to, let’s say, 500 of them, service providers will regard this as spam.

Remember! By sending letters to random users who didn’t consent to your mailing list, you risk ruining your brand’s reputation. The chances of getting results from an email campaign are much greater if the recipients voluntarily agreed to receive messages from you.
