What causes emails to bounce?
Email bounces fall under two categories: soft bounces and hard bounces. Soft bounces are temporary failures; they could mean the recipient’s inbox is full and cannot accept any new email, or they have set up an out-of-office, which resulted in an auto-reply. Hard bounces are permanent failures. And no matter how often you try to resend that email, it will not go through.
There are various reasons why an email will trigger a hard bounce; maybe the recipient has left the company, and the email address no longer exists. The recipient’s email address may have changed when the organization rebranded. An email bounce can also occur if the email address is a spam trap. However, the main causes of an email bounce are sending an email to an invalid email or an incorrect email address, which can happen if you simply have the wrong email address or the email address contains typos.
How do high email bounce rates affect my business?
High email bounce rates hurt your sender reputation, which relies on properly formatted email addresses, avoiding spam traps, no appearances on blocklists, and low email bounce rates. Sender reputation scores are assigned to your organization by an Internet Service Provider (ISP). The higher the score, the better for your email deliverability rates. Therefore, reducing your email bounce rate is crucial to keeping your IP address healthy.
Email bounces are inevitable in even the best email marketing campaigns. And bounce rates that are 2% or less is considered quite normal. However, should your bounce rates have crept past 2% or more, it’s time to take action.
How can I reduce email bounce rates?
