Block temp emails from your database with Arengu

Block temp emails from your database with Arengu

With the increasing number of data breaches and identity thefts in recent times, consumers are resorting to temp emails as an effective means to safeguard their privacy and data. While it can act as a magic bullet for the end user, temp emails are notorious for thwarting the marketing efforts of a business.

What are temp emails?

Temp emails or disposable emails allows one to receive emails at a temporary address instead of one’s primary email address. This helps avoid spam and ensure security. These throwaway emails become inactive after a specified period of time that typically ranges between 10 minutes and an hour.

How temp emails adversely affect your database

While temp emails work great for the end user, they spell disaster for a business that has them in its customer database. Below are the two main issues you must pay attention to:

1. Fake users in your subscriber list

Since there is technically no limit to the number of disposable emails a user can create, a business can never know the number of actual subscribers in their lists. This not only costs your business in terms of time and money spent on sending emails to disposable addresses, but can also mess up your email list analytics and impede your marketing efforts to reach out to genuine leads.

2. Hard bounces in your email campaign

A bounced email is never a good thing, we are all aware of that. Hard bounces? Even worse. Hard bounces are permanent delivery failures due to reasons like fake email addresses, fake domains etc. Do you know that your sender reputation will be at stake if you shoot email campaigns to disposable email addresses? Email sender reputation is a score assigned by an Internet Service Provider to any outgoing mail server. The kind of content you deliver, the number of times your emails are labeled or flagged as spam, subscriber engagement and bounce rate are crucial metrics that decide your reputation as a sender. It is thus imperative that you clean up temp emails from your database to improve your email deliverability and sender reputation score.
