In sales activities,the content of emails and the selection of target customers are important,but if emails don't even reach the recipient's inbox, it becomes difficult for them to read them.

There are various reasons why sales emails end up in the spam folder, including authentication settings for the sending domain, the volume of emails sent,the quality of the email address, and the content of the email body.

This article will introduce five common reasons why sales emails are filtered into spam folders, and provide specific measures to improve email deliverability.

1. Insufficient authentication settings for the sending domain.

One reason why sales emails end up in the spam folder is the authentication settings of the sending domain.

Email receiving services utilize various authentication technologies to verify the legitimacy of the sender.

The three most important are SPF,DKIM and DMARC.

• SPF: A mechanism that verifies which servers are authorized to send emails from a given domain.

• DKIM: A system that adds digital signatures to emails to verify the authenticity of the sender and the message.

• DMARC: A mechanism that verifies the consistency between SPF and DKIM authentication results and the sending domain, and specifies how to handle emails that fail authentication.

If these settings are missing or there are errors in the DNS records,your emails may be rejected or classified as spam.

Points for improvement

First,check your domain's DNS settings and verify that the authentication required for your email service is configured correctly.

In addition to adding settings,it's also important to check the authentication results of emails you actually send.

Google's official guidelines also provide instructions to senders on how to set up email verification and use appropriate sending methods.

2. They are drastically increasing the amount of data being transmitted.

Are you sending out a large volume of sales emails in a short period of time from a new domain or email account?

If an account that previously sent only a small number of emails suddenly starts sending a large volume of emails, the recipient's system may detect this as suspicious activity.

A high volume of emails doesn't automatically make them spam.However,if the volume increases unnaturally in relation to the domain's usage history and recipient response rate,it can negatively impact delivery.

Points for improvement

When starting to use a new sending environment, be sure to check the sending limits and sender guidelines of the email service.

Also,please check the following items regularly.

• Has the volume of transmissions increased sharply in a short period of time?

• Has the bounce rate increased?

• Are there increasing complaints about spam emails?

• Have you received any delivery error or restriction notifications from the recipient?

There is no single safe transmission limit that applies to all domains.It is important to operate appropriately while monitoring transmission results,rather than simply aiming to increase transmission volume.

3. High bounce rate

A bounce occurs when an email that has been sent is not delivered to the recipient and is returned as an error.

If your sales list contains many incorrect or outdated email addresses,you are more likely to experience bounces.

For example, consider the following case:

• There is a mistake in the email address you entered.

• We are using the old email address of a former employee.

• The sales list hasn't been updated in a long time.

• It is repeatedly sending messages to a non-existent address.

Leaving a high bounce rate unaddressed can negatively impact your reputation as a sender.

Points for improvement

Before sending out sales emails,make sure to check the quality of your list.

Using an email address verification tool to stop sending emails to addresses that have permanent delivery errors is also an effective strategy.

However, even if the email address verification is successful,this does not guarantee actual delivery or arrival in the inbox.

Make it a habit to regularly update your list and record changes in bounce rates.

4. The email body contains many unnatural elements.

The content of a sales email can also influence whether it's classified as spam.

For example, if a short message contains numerous links or images,or uses URLs unrelated to the content,the recipient's filter may become suspicious.

Furthermore,repeatedly using irrelevant advertising slogans or engaging in overly aggressive sales tactics can also lead to complaints from recipients.

However,simply including links or images doesn't automatically make an email spam.Multiple factors are involved, including the sender's reputation and the recipient's reaction.

Points for improvement

Sales emails should be written in a way that allows the recipient to understand the content quickly.

• Explain the reason for contacting me specifically.

• Provide information related to the other party's business.

• Reduce unnecessary links and images.

• Verify that the linked page is safe and matches the content of the text.

• We will appropriately respond to requests to unsubscribe and complaints from recipients.

Rather than cramming in a long company introduction, a sales email that concisely conveys the benefits for the recipient will be easier to read.

5. The main domain and the business-use sending environment are not properly managed.

You should also be careful if you are sending out a large number of new sales emails from your main domain,which you normally use for internal communication and customer support.

For example, if you use the same domain for sending out emails for new business development as the one used for communication among employees and this leads to an increase in complaints and delivery errors for sales emails,it could potentially affect emails used for regular business operations as well.

Therefore,some companies separate their transmission environments for general business use and sales activities, managing them according to their respective purposes.

However,simply adding a business domain is not enough.Even with a new domain, you need to properly manage authentication settings,sender trustworthiness,list quality and recipient response.

Points for improvement

First, let's organize your current sending environment and check which domains and email accounts you are sending emails from and what kind of emails you are sending.

When setting up a transmission environment for business use,it is important to manage the following items together.

• Domain and mailbox management

• SPF, DKIM and DMARC settings

• Monitoring of transmission volume and delivery results

• Handling bounces and complaints

• Checking the impact on regular business emails.

What's important is not simply increasing the number of domains or email accounts,but rather establishing the right infrastructure and continuing to manage emails in a way that considers the recipient.

Summary: Checklist for improving your sales emails,starting this week

There isn't just one reason why sales emails end up in your spam folder.Multiple issues may be contributing to the problem.

First,let's check the following five points.

This week's checklist

• □ Check the settings and authentication results for SPF, DKIM and DMARC.
• □ Check if the amount of data being transmitted has increased suddenly.
• □ Review the sales list and check the bounce rate.
• □ Organize links and images in the text to make the content easier to understand.
• □ Properly manage the main domain and the sending environment for business purposes.

You don't need to change everything at once.Start by checking your authentication settings and bounce rate and then improve the items where you find problems.

Improving email deliverability requires not only special techniques,but also basic settings and continuous management.

Checking daily sending results and delivering emails that are valuable to recipients forms the foundation of long-term sales activities.
