Ever reached out to prospects, only to find out your G Suite emails going to spam folder? This sounds unprofessional and not so helpful at the same time. If we see the bigger picture, it means your mails vanished in thin air. But don’t worry, I’m here to help. This blog post will provide you with easy fixes so that you can ensure your emails are landing in the inbox.
Understanding Spam Filters
Spam filters are like watchmen. They’re the gatekeepers literally. They decide which emails get through and which do not. Email companies spend millions to develop a sensible spam filtering system.
We can’t really guess why your email marked as spam by Gmail or any other email service. If it was that easy to guess this, hackers would have had a big advantage. However, these factors can increase our chances of getting through spam filters:
- Sender’s email
- Internet Protocol Address
- Message content
- Authentication protocol
Some of these terms might sound like Greek to you. In that case, keep reading and I’ll show you how we can have better luck with these spam filters.
Fixing Gmail Spam Issues
Domain Authentication
When it comes to email delivery, domain authentication is underrated. Most marketers don’t even authenticate and wonder why G Suite emails going to spam. If you’re among these marketers, let me give you a reality check! Domain authentication is like showing an ID to these spam filtering gatekeepers. It proves you’re who you say you are.
As of now, there are only 3 key protocols that you should focus on to increase your deliverability:
- SPF: Prevents email spoofing by verifying that the sending server is authorized to send emails to a specific domain.
- DKIM: Verify the authenticity of an email and its sender by using cryptographic signatures.
- DMARC: A policy framework that combines DKIM and SPF to provide email authentication and specify how email providers should handle messages that fail authentication.
Now that you understand what these 3 protocols are, update these given codes in your domain’s TXT records:
- SPF: v=spf1 includesp:_f.google.com ~all
- DKIM: You have to generate this key yourself within G Suite
- DMARC: v=DMARC1; p=reject; rua=mailto:info@yourdomain.com (make sure you add your email here)
That’s all you need for proper domain authentication.
Dealing with Blacklists
IP and Domain are the two key components of blacklists. Whether you’re blacklisted or not, you may try entering your IP and Domain on MXToolBox.

Make sure everything is okay. Just in case you’re blacklisted for some reason, your IP is less likely to be the concern here. Since we’re talking about G Suite emails going to spam, your IP shouldn’t be a concern because Google doesn’t operate on spammy IP addresses. It’s true that G Suite uses shared IPs, which might affect other users if one user sends spam emails. On the contrary, G Suite utilizes an IP rotation system that’s a surefire fix to this problem.
If IP isn’t the problem, it means that you’re mostly spamming cold emails and you have to give it some days to cool off. Usually, it takes a month. That’s why I advise marketers that they should not use their main domain names. Instead of mail@nowdigitaleasy.com, I’d recommend mail@digitaleasy.co or something else. Whatever it is, pick something different so that it can’t affect your main domain name.
Make Your Email Legit
Here’s something that’s coming from my personal experience. Make sure you keep a check on these things to not let your email marked as spam by Gmail.
- Never include links in your first email
- Have a proper signature at the bottom
- Be as specific as you can be
- Avoid salessy jargons or prohibited words like ‘guaranteed’ or ‘easy money’
Warm Up Your Inbox
Before I tell you about the warmup process, let me tell you that G Suite trial accounts can send up to 500 messages a day. On the other hand, paid accounts can send up to 2K messages a day.
Now that’s something which Google said. In reality, you shouldn’t start sending 500 or 200 messages a day right away. Instead, you should stick to this plan where you should increase the no. of emails sent gradually.
Day | Number of Emails | Frequency | Additional Notes |
1 | 10 | Once | |
2 | 15 | Once | Gradually increase the number of recipients |
3 | 20 | Once | |
4 | 25 | Twice | Divide the total number between morning and evening |
5 | 30 | Twice | |
6 | 35 | Twice | Continue increasing the frequency |
7 | 40 | Thrice | |
8 | 45 | Thrice | |
9 | 50 | Thrice | Gradually increase the total number of emails |
10 | 55 | Four times | Distribute throughout the day |
11 | 60 | Four times | |
12 | 65 | Four times | Continue increasing the frequency |
13 | 70 | Five times | |
14 | 75 | Five times | |
15 | 80 | Five times | Gradually increase the total number of emails |
Also, sticking to this plan only works on one condition. When you start sending emails, do your best to get a reply from the other side. If your reply rate is poor, be ready to see your email marked as spam by Gmail.
If inconsistency of G Suite’s IP rotation might cause trouble to you, you can rely on MailGun SMTP. Although setting it up has a learning curve, you’ll be surprised with the results. Plus, it might cost you a little extra which is fair to be honest. After all, getting into the inbox is the best thing. You get to close more clients.
