Understanding Email Checkers: A Video Overview
Email is such an extensive discipline. The creation of a powerful tool called email had the same life-altering communication power as telephones when they were first created. To date, email newsletters and sales pitches are still one of the most promising and cost-effective digital marketing approaches to generate more income for your business online.
Harnessing emails as a marketing channel is critical to every business and industry. If you’re wondering how to create an email for a business, it’s essential to understand the key strategies and best practices involved in crafting effective business emails.
A robust email list for your business can provide a high conversion rate and return on investment (ROI). Managing a contact list is becoming more demanding as the email lists grow. Email verification is essential for every email marketing effort as it ensures that every email message is sent to each email address with precision and accuracy.
Emails sent to invalid or fake email addresses, whether a business or personal address, will get bounced back, affecting the whole deliverability score of your email marketing campaigns.
To ensure that your emails are adequately sent to their respective recipients, an email checker or email verification tool can reduce the email bounce rate and increase the deliverability rate (read the best practices for email deliverability), especially when sending bulk email newsletters to your email list.
What is an Email Checker?
An email checker is a software used to check the validity of email addresses to ensure that email campaigns are sent to legitimate email addresses. Email checker tools:
- Validates email addresses to ensure campaigns are sent to legitimate recipients.
- Supports bulk uploads of email lists for verification through multiple checks.
- Verifies domain structure and mailbox existence with Internet service providers.
- Provides downloadable results of cleaned, up-to-date, and verified lists.
- Removes fake, inactive, and invalid emails from the email list, reducing bounce rates and improving deliverability.
- Saves money and prevents costly mistakes by avoiding campaigns sent to dead or fake addresses.
- Detects disposable/temporary emails, often used by scammers or bots.
- Prevents spam folder issues by keeping lists accurate and active.
- Validates user-submitted emails in web forms before adding them to mailing lists.
