Lets Sort Your Email DeliverabilityEmail Deliverability Test & Best Practices to Improve Inbox Placement
1. Stay on Top of SPF, DKIM, and DMARC
Strong email deliverability often starts with constant attention to authentication. You need to set up SPF, DKIM, and DMARC correctly, then monitor them to block spoofing and misuse. Whenever you add a new vendor or change your infrastructure, remember to audit the settings right away. To push trust even further, add BIMI so your logo shows in the inbox and makes your emails stand out instantly. Running the occasional email deliverability test can help confirm the authenticity of your email and ultimately won’t have a negative impact on inbox placement.
2. Protect Deliverability with List Hygiene
We all know that a healthy list is the backbone of strong deliverability. But when was the last time you properly cleaned it?
It always pays back in deliverability scores to remove anyone who’s inactive or unengaged. You can suppress hard bounces, spam complaints, and invalid addresses right away so your sender reputation stays strong. In fact, you can pair list hygiene with an email deliverability test to keep your progress in check. And when possible, use double opt-in to confirm new sign-ups. This keeps your list full of real, engaged subscribers.
3. Stick to a Steady Sending Rhythm
Consistency keeps your emails out of trouble and in the inbox. Sticking to a steady sending schedule will steer clear of creating sudden spikes that hurt engagement. Keep an eye on opt-in sources to block low-quality contacts from sneaking in. And before you import any contacts manually, always validate and maintain list hygiene so you don’t add dead addresses. This can save you from turning into spam traps.
4. Always Get Clear Opt-Ins
In a world that is screaming for attention, asking for permission is the foundation of good email marketing (and any sort of good marketing by extension). It’s always good to focus on quality by ensuring every subscriber has clearly opted in. Set the right expectation at sign-up so people know what they’ll receive. This is easy to keep engagement high and unsubscribe rates low.
5. Send Value-Driven, Relevant Content
It’s no secret that engagement drives deliverability, so make every email worth opening. Optimize your content to boost clicks and opens, since low interaction can push messages out of the inbox. You need to personalize subject lines, preview text, and messaging around each subscriber’s behavior and preferences. And then check different elements like subject lines, CTAs, or email length to see what works best and if your email is landing in your consumers' inboxes. And most importantly, skip the generic promos and focus on content that feels valuable and relevant to your audience.
6. Protect Your Domain from Blacklist Damage
Blacklists can sink deliverability fast. So it’s crucial to stay ahead of them. You need to regularly check your IPs and domains against major lists like Spamhaus, Barracuda, or SURBL on a regular basis. And if you ever get flagged, dig into the root caus. Is it spam complaints, weak engagement, or authentication gaps? You would need to fix everything quickly before asking for delisting. To avoid any surprises, simply set up monitoring tools that send real-time alerts the moment your domain or IP lands on a blacklist, and preferably run periodic email deliverability tests to stay informed about your inbox placement performance.
7. Let Data and Feedback Drive Your Strategy
Data never lies. Strong deliverability comes from listening to the data and acting on the feedback. If your subject lines are spiking open rates but CTR remains low, it means that the hook is working, but the content is not. This is your signal to make the content more relevant and engaging. But that’s not all. Watch your sending frequency, too. A spike in unsubscribes or spam complaints is a clear sign you’re sending too often. Scaling back will help keep your audience happy. This is also where you can pivot to experiment mode and test the design, CTAs, wordings, placement, and styles until you figure out what performs best And once you have made these improvements, you can finally run an email deliverability test to check how your email updates are performing in terms of email inbox placements. All this effort will eventually protect your sender reputation and keep landing your emails in the inbox.
8. Ditch Free Addresses for Business Emails
It pays to always use a custom domain for business emails. Free addresses like Gmail or Outlook can look unprofessional and even trigger spam filters, leaving a big dent in your marketing. The issue is that free platforms are not designed for bulk sending, making deliverability risks even higher. Instead, choose a reputable ESP like Flodesk or MailerLite that can handle spam filtering, bounce management, and list hygiene for you. And don’t forget to maintain or even improve your domain reputation by using an email deliverability test tool. Always remember, a domain with a poor history will make it harder for your emails to land in the right inbox at the right time.
9. Boost Deliverability with Warm-Up Tools
Warming up your email is key to better deliverability. The right email deliverability test tools can make the process smooth and effective. Platforms like lemlist help you build personalized, multichannel campaigns that boost engagement from the start. Its Smart Enrichment feature pulls valid email and LinkedIn details, saving you time and effort. More importantly, its Warm-up & Deliverability Booster steadily builds your sender reputation so your emails land in the inbox instead of the spam folder. Getting this step right sets the tone for the entire campaign.
10. Protect Reputation by Growing Organically
Never buy or rent email lists if you care about deliverability. These lists are often scraped through shady methods and can include spam traps set up to catch bad senders. Hitting those traps can tank your IP and domain reputation, and fixing the damage takes time and effort. Even worse, most purchased lists are full of unresponsive or unqualified contacts, so they won’t help your marketing anyway. Instead, focus on building your own engaged list. If you want to scale smarter, use tools like lemlist for multichannel outreach and CRM integrations that keep your campaigns effective and reputation safe.

FAQs
An email deliverability test checks to see if your emails are actually getting to their intended recipients and not just being sent. It tells you if your emails go to the main inbox, the promotions tab, or the spam folder in Gmail, Outlook, and Yahoo, among other email services. This helps you find problems with your setup, your list, or how you send emails.
You can use the free InboxArmy Email Deliverability Test to instantly check how your email performs across Gmail, Outlook, Yahoo, and more.
Our free deliverability test tool sends your email to a group of test addresses on different email services. This tells you where your message ends up: in the inbox, in the spam folder, or blocked. Our tool also looks at your domain and IP reputation, authentication settings like SPF, DKIM, and DMARC, and checks your content for problems. With our test, you simply add a snippet of code to your email and send it to the test addresses we provide. The report then shows inbox vs. spam placement, authentication results, spam score, and blacklist status.
If your deliverability score is low, it's likely that your emails are being marked as spam or blocked. If you follow these steps every time, your inbox placement should get better over time:
- Check to see if you are who you say you are: Check that SPF, DKIM, and DMARC are all set up correctly and working together.
- Make your list clean: Delete contacts that are invalid, inactive, or not engaged. This makes fewer people bounce and complain about spam.
- Look over your sending habits: Don’t send to purchased lists, don’t send too many emails at once, and don’t send too many emails overall.
- Make your content better: Stay away from spammy words, look for broken links, and make sure there is a good balance between text and images.
- Be careful with your reputation: If your IP or domain reputation is bad, use warm-up tools or change the domains you send from.
Not all the time. Most tools for deliverability are made to be simple to use. You can usually do a test by either uploading your email list or sending it to a test list. You don't need to know a lot about technology to do that part.
For instance, we have seen that most users find the InboxArmy Email Deliverability Checker you see above simple to run. There is no coding knowledge needed. And for advanced fixes (like DNS or blacklist issues), the tool highlights what’s wrong so your team can act quickly.
Yes, absolutely! Our tool above generates a shareable link that you can easily share with anyone in your team to keep them aligned and informed. Try clicking on “Example Report” to see how it works. Then click on “Share Report” to see the available options. You’ll see that you can even directly share the report via Email, Whatsapp, or other social media channels like X (Twitter), Linkedin, Facebook, etc.
There are a few main reasons why emails end up in spam, and they mostly have to do with how trustworthy and relevant you seem to inbox providers. One of the biggest problems is that the sender has a bad reputation. If you get a lot of bounces or spam complaints, this can happen. Filters also get suspicious when authentication is missing or set up wrong (like SPF, DKIM, or DMARC). Low engagement is important too. Providers see it as a bad sign if people don't open, delete, or ignore your emails very often. Spam filters can also be set off by your content, such as having too many links, subject lines that are misleading, or words like "FREE" or "URGENT." Your emails might get blocked or sent straight to spam without warning if your domain or IP ends up on a spam blacklist.

Our company needed to revamp our entire email system for our main brand of bicycles, Sixthreezero. We hired InboxArmy to build out new automated flows, post purchase email flows, marketing campaigns, and anything else we could come up with to stimulate our sales. I worked with the director and his designers to develop the emails that would connect with our target market. InboxArmy managed me, I literally had to keep up with how fast they work.
Immediate increase in revenues, our return customer conversion rate increased by roughly 50%, and our open to click rates all increased. The ROI was about 26 to 1. Zero complaints, our resources were not wasted hiring InboxArmy.
