Email Deliverability Services: Fix Emails Going to Spam, Junk or Blacklists
Your emails are leaving your outbox. The question is whether they are arriving anywhere useful.

When business emails land in spam folders, bounce silently, or never arrive at all, the impact is immediate — missed leads, unanswered proposals, customers who never received what they were waiting for, and a sales or marketing pipeline quietly draining in the background. Most businesses only discover there is a problem when someone mentions it by chance, or when campaign results become impossible to explain.
Yeevu’s email deliverability service exists to fix that. We diagnose every factor affecting your inbox placement, repair what is broken, and configure your sending infrastructure the way inbox providers expect it to be so your emails reach the people they are meant for, every time.
Whether you need to improve email deliverability across your campaigns, fix email deliverability issues that have emerged suddenly, or build a new sending infrastructure correctly from day one, this is what we do.
01
Stop Emails Going to Spam or Junk
If your emails are going to the junk folder, landing in spam, or simply not being delivered at all, you are not alone; and the problem is almost never the content of the email.;
Inbox providers like Gmail, Outlook, and Yahoo use a complex set of signals to decide where an email lands. Authentication failures, poor sender reputation, sudden spikes in sending volume, high unsubscribe or complaint rates, and missing or misconfigured DNS records all contribute to emails going to junk or spam mail rather than the inbox. In many cases, multiple factors are at play simultaneously — which is why trying to fix one thing in isolation rarely produces lasting results.
The most common reasons business email ends up in the spam or junk folder include:
Missing or broken authentication records.
If your SPF, DKIM, or DMARC records are absent, misaligned, or configured incorrectly, inbox providers have no technical basis for trusting that your email is legitimate. Gmail and Outlook in particular are increasingly aggressive about filtering email that fails authentication and the threshold for what counts as a failure is stricter than it was even two years ago.
Sending from a domain with no history.
A domain that jumps from zero sending to high-volume campaigns without a structured warm-up period triggers exactly the pattern inbox providers associate with spam operations. Emails going to spam on a new domain almost always have this as the root cause.
Shared infrastructure with a damaged reputation.
If your emails travel through shared IP addresses — as they do on most standard hosting email and many entry-level ESPs — the behaviour of other senders on those same IPs affects your deliverability. One bad actor on a shared IP can push email landing in spam for every business using it.
Engagement signals working against you.
Inbox providers track whether recipients open, click, delete without reading, or mark as spam. A sending history with poor engagement signals — often the result of sending to stale or unvalidated lists — tells inbox providers that your emails are not wanted, regardless of whether any individual recipient has complained.
Business email not being delivered due to DNS mismatches.
When DNS records are changed for a migration or a new tool is added without updating SPF, the result is authentication failures that cause business email not to be delivered — sometimes for days before anyone realises.
We identify which of these factors are affecting your deliverability, in what combination, and fix them in the right order.
02
Email Blacklist Removal
One of the first questions businesses ask when deliverability problems emerge is: is my email address blacklisted?
Blacklisting — more accurately, domain or IP blocklisting — occurs when a spam monitoring organisation or inbox provider adds your sending domain or IP address to a database of known or suspected spam sources. Once listed, emails from the affected domain or IP are filtered or rejected by inbox providers that consult that database. The damage can range from reduced inbox placement to complete rejection of all outgoing mail.
Blacklistings happen for a variety of reasons. A spam complaint rate that crossed a threshold. A period of sending to purchased or outdated lists. A security incident that allowed your domain to be used for spam without your knowledge. Shared infrastructure where another sender’s behaviour resulted in the IP being listed. In some cases, businesses are listed on minor blacklists they have never heard of and would never have known about without running the right checks.
Our blacklist investigation and removal service covers:
Checking your sending domains and IP addresses across all major blacklist databases, not just the handful that are commonly checked, but the full range of lists that inbox providers and corporate mail filters actually consult. Identifying the specific list or lists your domain or IP has appeared on. Determining what triggered the listing and whether the underlying cause has been resolved or still needs addressing. Submitting delisting requests to the relevant blacklist operators, with the supporting evidence and context those requests require to be processed successfully. Monitoring to confirm removal and to catch any re-listing that occurs during the recovery period.
Blacklist removal is not always instant. Different operators have different processes and timelines. We manage the process and keep you informed throughout, so you are not left wondering what is happening or whether anything is being done.
Email Reputation Repair
Blacklist removal resolves a specific, identifiable listing. Email reputation repair addresses something broader and more fundamental: the accumulated signals across your sending history that determine how inbox providers treat your email by default.
Sender reputation is the aggregate assessment of your domain and IP as a source of email built from authentication record health, complaint rates, engagement rates, bounce rates, blacklist history, sending volume patterns, and the age and consistency of your sending behavior. It is not a number you can look up in one place. It is a composite picture formed by each inbox provider independently, from their own data and third-party signals.
Our sender reputation diagnostics cover:
Domain reputation assessment. We evaluate the health of your sending domain’s reputation across major inbox providers, using tools that reflect how Gmail, Outlook, and Yahoo are actually scoring your domain based on historical sending behaviour.
IP reputation review. Whether you are sending from shared or dedicated IP addresses, we assess the reputation of the infrastructure your email travels through — identifying whether IP-level issues are contributing to your deliverability problems and what remediation looks like.
Spam filter and blocklist investigation. Beyond major blacklists, we investigate whether your domain or IP has appeared on the specialist blocklists and spam filter databases that corporate mail filters and security gateways consult — sources that are not visible in standard blacklist checks but frequently contribute to business email deliverability failures in enterprise environments.
Reputation repair planning. Where reputation damage has accumulated over time, recovery requires a structured approach — not a single fix but a sequence of interventions that address the underlying causes, clean up the sending history, and rebuild positive engagement signals over a defined timeframe. We design that plan based on the specific state of your reputation and your sending requirements, and we can support you through the recovery process if needed.
SPF, DKIM and DMARC Setup
SPF, DKIM, and DMARC are the three DNS-based authentication standards that inbox providers use to verify that emails from your domain are legitimate. Configuring SPF, DKIM, and DMARC correctly is the single most impactful technical step most businesses can take to improve deliverability — and one of the most commonly done incorrectly.
SPF (Sender Policy Framework) defines which mail servers are authorised to send email on behalf of your domain. A correctly configured SPF record lists every sending source — your business email platform, your email marketing tool, your transactional email service, your CRM — without exceeding the DNS lookup limit that causes SPF evaluation to fail. An SPF record that is missing, too permissive, too restrictive, or structured incorrectly causes authentication failures that directly suppress inbox placement.
DKIM (DomainKeys Identified Mail) works by attaching a cryptographic signature to every outgoing email that receiving servers can verify against a public key published in your DNS. When DKIM is correctly configured for every platform sending email from your domain, it provides inbox providers with strong evidence that your emails are legitimate and have not been modified in transit. Missing or incorrectly implemented DKIM is one of the most common causes of email landing in spam despite clean content and a good list.
DMARC (Domain-based Message Authentication, Reporting and Conformance) builds on SPF and DKIM by giving you a published policy that tells receiving servers what to do with emails that fail authentication — and by providing reporting that shows you exactly what is happening across your domain’s email activity. A properly configured DMARC record, aligned with your SPF and DKIM setup and set at the right enforcement level for your current infrastructure, is essential both for inbox placement and for protecting your domain against spoofing and phishing attacks that use your brand without your knowledge.
Our SPF, DKIM, and DMARC setup service covers every aspect of getting all three layers correctly configured, aligned with each other, and validated across your full sending infrastructure — with reporting in place so you have ongoing visibility into your authentication activity.

How the Email Deliverability Services Work
1. Email Deliverability Audit
We begin with a comprehensive audit of your current email sending setup — documenting every sending source, reviewing existing DNS records, assessing your sending history, and identifying the symptoms you are experiencing. This gives us a complete picture of where things stand before we make any changes.
2. Blacklist and Reputation Checks
We run your sending domains and IP addresses through a full suite of blacklist databases and reputation assessment tools — covering major blocklists, inbox provider reputation scoring, and the specialist databases that corporate and enterprise mail environments consult. Every issue identified is documented with context on severity and priority.
3. SPF, DKIM and DMARC Verification
We audit your existing authentication records for correctness, alignment, and completeness. We check SPF for lookup limit compliance and correct authorisation of all sending sources. We verify DKIM signing for every connected platform. We assess DMARC policy level, record syntax, and reporting configuration — and identify precisely what needs to change to achieve correct authentication alignment across your full sending infrastructure.
4. DNS and Mailbox Remediation
We implement the DNS changes and platform configurations identified during the audit — updating or creating SPF, DKIM, and DMARC records, resolving MX record issues, correcting any other DNS-level factors contributing to deliverability problems, and configuring sending platforms correctly within the authenticated infrastructure. Every change is documented and validated before sign-off.
5. Spam Placement Testing
Once remediation is complete, we run inbox placement tests across major providers including Gmail, Outlook, and Yahoo — verifying that emails from your configured infrastructure are landing in inboxes rather than spam or junk folders before any live sending resumes at scale.
6. Monitoring and Follow-Up Recommendations
We provide post-remediation monitoring to confirm the fix is holding and to catch any secondary issues that emerge as sending resumes. Where reputation repair requires ongoing management over a longer period — for example, a structured warm-up programme following a blacklisting recovery — we provide a detailed plan and can remain engaged to support the process through to completion.

Frequently Asked Questions
Why do my emails go to spam or junk mail?
Emails land in spam or junk mail for a combination of technical and reputational reasons. The most common technical causes are missing or misconfigured SPF, DKIM, or DMARC records — which prevent inbox providers from verifying that your emails are legitimate. Reputational causes include a poor sending history, shared infrastructure with a damaged IP reputation, high spam complaint rates, or sending to outdated or unvalidated lists. In most cases, multiple factors are contributing simultaneously, which is why fixing one thing in isolation rarely resolves the problem fully.
How do I fix Gmail emails going to junk and spam?
Gmail uses a combination of authentication signals, sender reputation, and engagement history to filter email. Fixing Gmail deliverability issues typically involves ensuring SPF, DKIM, and DMARC are correctly configured and aligned, checking whether your sending domain or IP appears on any blocklists Gmail consults, reviewing your sending history for patterns that may have triggered reputation damage, and running inbox placement tests to confirm the fix has taken effect. Our email deliverability service covers all of these steps as a structured process rather than isolated fixes.
Who can help when my emails continue going to spam?
If your emails continue going to spam despite changes you have already tried, it is usually a sign that either the root cause has not been correctly identified or that multiple overlapping issues are present. Yeevu’s email deliverability service provides a systematic audit of every factor affecting your inbox placement — authentication, reputation, blacklisting, infrastructure, and sending behaviour — and implements fixes in the right sequence. Contact us to describe what you are experiencing and we will tell you how we can help.
Where is the spam folder in email?
In Gmail, the spam folder appears in the left-hand sidebar labelled Spam. In Outlook, it is labelled Junk Email and also appears in the sidebar. In Apple Mail, it is labelled Junk. In Yahoo Mail, it is labelled Spam. On mobile apps, the spam or junk folder is typically accessible by tapping the menu or folder icon and scrolling through the folder list. If you are asking because recipients are not finding your emails, ask them to check their spam or junk folder — and see the final FAQ below for guidance on what to tell them.
Why is my business email not being delivered?
Business email that is not being delivered (meaning it does not arrive in the inbox or spam folder at all) is typically the result of a hard bounce, an MX record misconfiguration, an SPF failure causing rejection at the server level, or a blacklisting that causes the receiving server to reject the connection entirely rather than filtering the message to spam. If your business email is not being delivered to specific recipients or domains, we can run diagnostics to identify exactly where the delivery chain is breaking down and what is causing it.
How do I know if my email address is blacklisted?
You can check basic blacklist status using free tools like our email deliverability checker tool, which checks a small number of the most commonly referenced lists. However, a clean result on a basic check does not mean your domain or IP is not listed elsewhere. There are dozens of blocklists in active use, and the ones that affect deliverability in corporate and enterprise environments are often not covered by free checkers. Yeevu’s blacklist investigation service checks your sending domains and IP addresses across the full range of lists that inbox providers and mail filters actually consult, giving you a complete and accurate picture rather than a partial one.
Should recipients check their spam or junk folder for my email?
If your emails are going to spam, it is reasonable to ask recipients to check their spam or junk folder as a short-term measure — but it is not a solution. Asking people to look for your email in their junk folder every time they expect to hear from you is a poor experience that erodes trust, and it does nothing to address the underlying deliverability problem. The correct approach is to fix the root cause so your emails stop landing in spam in the first place. In the meantime, if you ask recipients to check their junk folder, also ask them to mark the email as not spam or move it to their inbox — this generates a positive engagement signal that helps your sender reputation over time. Your email should always arrive in the inbox, not require recipients to go looking for it in junk.
How much do email deliverability services cost?
It depends on what the diagnosis finds — a straightforward authentication fix is a smaller engagement than a reputation recovery across several domains. Every engagement starts with an audit, and you receive a written quote with the full cost before any remediation work begins.
Do you guarantee inbox placement?
No — and no honest provider can, because mailbox providers make the final filtering decision. What we do stand behind is verifiable work: authentication correctly configured and aligned, blocklist issues addressed, and spam placement tested before and after remediation so you can see the improvement.
Do I need an email deliverability consultant?
If deliverability problems keep returning after one-off fixes, a consultant-led review is usually what finds the overlapping causes. Yeevu acts as your email deliverability consultant for the engagement: we diagnose the full picture, carry out the fixes, and verify the results rather than handing you a report and leaving.
