Reputation repair

Emails going to spam? We'll get you back to the inbox.

Q: How do I stop my emails going to spam?

Find and fix the cause first. Correct SPF, DKIM and DMARC, remove addresses that bounce or never engage, and cut volume back to your most engaged recipients for a while. Then rebuild slowly with consistent, wanted mail. Sending more while you're in spam usually digs the hole deeper.

Q: My domain is blacklisted. What should I do?

Run the free Blacklist Checker to see which lists flag you. Then fix what caused the listing, which is often a compromised form, a purchased list or spam-trap hits. Only after that should you request removal from each list. If you work with us, we handle the delisting requests and the clean-up.

Q: How long does sender reputation repair take?

It depends on how badly the reputation is damaged and how fast the cause is fixed. A single listing with a clear cause can clear in days. A domain that Gmail has been filtering for months needs several weeks of consistent behaviour before providers trust it again. We won't promise a fixed date, because no one can, but we set milestones so you can see progress week by week.

Q: Why are my Gmail emails going to spam but not Outlook?

Each provider weighs signals differently. Gmail leans heavily on how its users engage with your mail and on your domain's history there. Outlook relies more on its own filters and complaint data. That's why we test placement per provider and fix the provider that's failing.

Q: Should I just switch to a new domain?

Usually not. A new domain has no reputation, still needs warming up, and will end up in spam too if the cause isn't fixed. Repairing your current domain is often faster, and your recipients keep recognising the sender.

Q: How much does sender reputation repair cost?

It depends on how many domains and mailboxes are affected and what's causing the problem. Book a demo and we'll look at your setup and give you a quote after the first review.

Q: Can you get my domain removed from Spamhaus?

We prepare and file the removal request with you, but only Spamhaus can remove a listing. They expect the cause to be fixed first, so most of the work is finding and fixing what triggered it. Once that's done, removal requests usually go through quickly.

Q: Do you fix Microsoft and Outlook blocks too?

Yes. Outlook and Hotmail blocks have their own causes and their own delisting process, separate from Gmail's. We test placement at Microsoft separately and include it in the recovery plan when it's part of the problem.

Diagnosis

Why your emails are going to spam

Spam placement has a cause. We look at the four places it almost always comes from, and tell you exactly which one is hurting you.

Content
Spam-trigger words, heavy images, broken links or tracking domains that filters distrust.
Infrastructure
Missing or broken SPF, DKIM and DMARC, misaligned domains, bad reverse DNS or a shared IP with a poor record.
List quality
Bounces, spam traps, old or purchased contacts, and recipients who mark you as spam.
Sending history
Sudden volume spikes, a cold new domain, or past complaints that still weigh on your reputation.

Sender reputation repair: when you need it and what's included

Sender reputation is the record mailbox providers keep of how your domain and IPs behave. Once it drops, Gmail, Outlook and Yahoo start filtering your mail to spam or refusing it, and every new campaign makes the record worse. Reputation repair stops the slide, fixes the cause and rebuilds trust in a controlled way.

Signs your emails are going to spam because of reputation

The pattern is usually sudden. Open rates fall by half in a week with no change to content. Gmail recipients find your mail in spam while Outlook users still get it, or the other way round. Bounces start carrying codes like 550 5.7.1 or messages that mention your domain's reputation. Google Postmaster Tools shows a rising spam rate, or the Blacklist Checker finds your domain or IP on Spamhaus. Any one of these is worth a look. Two or more together almost always point to a reputation problem.

What's included in reputation repair

Every engagement starts with placement tests across Gmail, Outlook, Yahoo and other providers, so you know where your mail lands today. Our team then audits SPF, DKIM, DMARC, reverse DNS and MX, checks your domain and IPs against the major blacklists and reviews list sources, bounce data and complaint rates. You get a written root-cause report and a recovery plan. We correct the records, file delisting requests, help clean the list and set a sending schedule that rebuilds positive signals through warm-up with real mailboxes. Monitoring runs throughout, with alerts if a signal drops again.

How long sender reputation recovery takes

It depends on the cause. A blacklist listing with a clear, fixed cause can clear in a few days. A damaged IP reputation usually needs a few weeks of steady, low-complaint sending. Domain reputation at Gmail is the slowest to move, and rebuilding it often takes several weeks of consistent warm-up and careful volume. We set milestones at the start so you can see progress in placement tests and Postmaster data week by week.

Repair it yourself or with Warmy

You can fix many issues alone with our free tools and guides, such as why your emails go to spam and how to improve sender reputation. It works when the cause is one broken record or one listing. When several causes overlap, or revenue depends on every send, a guided plan saves weeks of trial and error. Switching to a new domain rarely helps: it starts with no reputation, and the same habits damage it again.

Next step: find out how bad it is

Run the free Blacklist Checker and Domain Reputation Checker for a first read, then talk to a deliverability expert. A 30-minute call is enough to tell whether you need a full repair or a few fixes.

FAQ

Emails Going To Spam?
Questions, Answered

Why are my emails going to spam?

Almost always one of four causes, or a mix of them: content that looks like spam, broken authentication or DNS, a poor-quality list full of bounces, traps and complainers, or a damaged sending history. Reputation repair works out which one it is in your case.
