Why SendGrid Emails Going To Spam?

There are multiple reasons why SendGrid emails are going to spam, but every email marketer has a unique reason. Here, we are executing some reasons which are genuinely faced by SendGrid Users:

Not Setting SPF And DKIM

One of the main reasons why SendGrid emails are sent to Spam is, they are not verified properly. SPF and DKIM are the two effective mechanisms used to verify whether the email is sent from authentic users or not. If you do not insert these two tools for your email deliverability system, your email has a high chance to land in the spam folder.

Poor IP Reputation

Another main reason for getting SendGrid emails into spam is sending emails through blocked IP addresses. Recently, SendGrid users have complained about how inbox providers are blocking SendGrid’s IP address. This happens with sharing IP addresses. If a few marketers spam people, other genuine marketers with the same IP address will get affected.

Choosing The Wrong Customer Base

If you cannot figure out your efficient audience, the emails are bound to end up in the spam folder. For example, if your business is related to football, it will not be a wise decision to keep cricket enthusiasts in your recipient list. No cricket lover will love to get football news every day. As a result, they will send your email to the spam box.

Not Having The Great Customer Support

Although this issue is not linked directly to spam, it can play a vital role to delay the process of resolving it. Customer support needs to respond in adequate time. Otherwise, the inbox provider can consider your email spam. SendGrid users have complaints of poor customer service, which requires them to have more time to recover the issue.

Lack Of Sending Personalized And Relevant Content

If you are aware of how your users interact on your platform and do not send emails with personalized, interesting, and relevant content, then you are missing out on a big note. Nobody will like to see some old features of your product every day, and it will lead your email content to your spam folder.

Phishing Techniques

While sending emails, you have to be careful of phishing techniques. If your email contains any malicious links that cost the users to reveal some personal information, it will be known to contain phishing techniques. Thus the recipient will mark your email spam and ensure your SendGrid emails going to spam.


How To Prevent SendGrid Emails Going To Spam

Where there is a problem there is also a solution. You can avoid landing in recipients’ spam folder if you take care of some matters.

Build Your Customized Email List

Email content plays an essential role in communicating with the stakeholders with the information. But if it does not reach the recipient’s inbox, there is no use in getting the best content. Therefore to reduce emails from going to spam;

  • Do not rent, purchase, or co-register an email from a third party.
  • Never share your email list with partners.
  • Do not ever scrap or use robot tools to collect your email

Building your email list organically is the best way to get your best return for a long time. It perhaps is not the smoothest or fastest-growing method, but it will grow your audience most effectively.

Double Opt-In For Your Email

Verifying recipient registration is very essential to establish a healthy and sustainable email list. Using a double tap-in will allow you to send a confirmation or welcome message to ensure whether the subscriber has received the email or not. Using double opt-in will make your recipient interested in your emails. Besides, it will keep your engagement and delivery rate high while lowering spam rates.

Warmup Email Domain

Warming up your new email domain ensures your emails will end up in your recipients inbox. And using a warm up tool is always a better choice rather than manual warming up. Cause manual warm up takes 60-90 days. Where as, Warmbase takes only 14 days. Warmbase automatically warms up your email domain and makes sure your emails do not lands to recipients spam folder.

Authenticate Your Email List

Email authentication is tricky but the key factor is to verify whether you are sending legitimate emails or not. If your messages are authentic, inbox providers will not take any time to send them to your inbox. The following methods will authenticate your email:

  • SPF: It confirms your identity by doing a comparison between your domain Ip and another list of authorized IPs sent from that domain.
  • DKIM: it ensures that emails do not get tempered during the transmission process.
  • DMARC: It mainly leverages the power of SPF and DKIM by requiring them to send and deliver emails.
  • BIMI: It helps to attach your business log with your email, making your business more recognizable and authentic.

Clean Up Your Email List

There will always be some recipients in your list who just don't want to receive any email and send the email directly to the spam folder without even giving it a second thought. This is okay in the business and you should not keep them on your list. Keeping them on your list will hamper your reputation. Thus, do clean up your email list regularly. Observe who gets engaged to email and who stays inactive. Then, just remove them from the subscription list. Removing inactive users' bounce emails and spam traps is the most useful way to clean up your email list. Regular list nurturing will help to increase engagement and domain reputation.

Avoid Denying Emails And Monitor Your Domain Reputation

Your email domain has an important connection with your domain reputation. If by any chance the reputation begins to fall, the email will automatically get into the deny list. To reduce the risk of being on the email list, you can follow these trending tricks:

  • Using double opt-in will ensure the engaged recipients
  • To remove inactive and unengaged subscribers, it is better to use the sunset policy.
  • Use real-time validation tools to avoid the risk of being trapped with false emails.

Try to watch over your delivery rate so that it notifies you if your emails end up in the deny list.

Monitor Email Engagement Measurement Metric

Metric your email performance is the best way to know how your email is progressing and improving. To measure the performance with the metric you need to understand your metric baselines such as spam complaints, open rate, delivery rate, and click rate.

When you start to track these metrics, it can result negative. But, do not panic, try to analyze the subject line and email frequency. Mostly these two variables create an impact on the metric. Besides, while testing, try to use real content and recipients. Practice some seed testing too.

Be Compliant With Internet Privacy Law

Compliance does not have a direct impact on email delivery but it removes some ISP roadblocks. The most important compliance for marketers and senders is:

  • The CAN-SPAM compliance act 2003 restricted the flow of unsolicited emails in the 2000s and set a new standard to send commercial emails. CAN-SCAM is still in use and dictates how the messages reach the inbox.
  • Under this act, the sender must comply with some series of rules and legal obligations to send emails.
  • CASL on the other hand provides more similar functions to CAN-SPAM. It works to build a more transparent relationship between sender and recipient. CASL is mainly used for commercial electronic messages.
  • GDPR is probably the most hyped piece of privacy legislation that is at the top of the mind since its inception in 2016. It regulates to cover the entity of the EU. That means anyone sending emails to the region must need to be compliant.

However, CCPA is like the natural descendant of the above legislation. It grants consumers more power and control over the use of data. Remember, compliance with these laws and regulations is a mandatory obligation if you don't want to see yourself as a spammer.

Subject Line

A good and straightforward subject line can do a lot for your email deliverability. Remember CAM- SPAM legislation requires a clear subject line that does not confuse the recipient.

A clear subject line is the beginning of creating a good impression and every message you send will bring a new opportunity for engagement. A powerful subject line requires the following features;

  • Keep short and simple: The more it is simple and short, it will be better to catch the attention of the recipient.
  • Avoid clickbait: Any kind of language that sounds spammy and clickbait will directly send you to the spam folder. so, use clear language to get saved from being blocking.
  • Get creative: The same type of language as email will make the recipient feel bored. This is why try to experiment and find new ideas to make your email interesting.

Provide Email Preference Center

The email preference center allows the new and existing subscriber to set when and how often they want to get emails. Giving this power to them makes the recipient control how you contact them. Making subscription access easy will help to remove inactive subscribers and will reduce the risk of outer emails to mark as spam. This will also increase the engagement rate.

Send Relevant Content

The core of a successful email program depends on how relevant, unique, and interesting your content is. When you send emails, try to make them the best ones so that the receipt gets forced to take them into your inbox. Do not send emails just for the sake of sending them. It will hamper the engagement rate. Your messages must resonate with the recipient and need to be close to your business aim.

Use Quick Support Features

Slow and inactive customer support can be disappointing to the subscribers. Therefore try to speed up the support feature by using live chat instead of mail communication. Be descriptive about your product and tell them about your situation so that they can assist you. Try to search through their help guide to know whether their problem got solved or not. These quick support features will help to build a great relationship with your customer.

Utilize The Spam Checker

An online spam checker is a tool that helps you to test your emails and indicate how likely the recipient will send the emails to the spam folder. Although ISPs take the final decision regarding spam filters, spam checkers will relax the sender as they are preparing for a new campaign.
