How to Stop Your Email Going to Spam
How to diagnose why your mail gets filtered and rebuild its reputation the right way, without the guessing — the steps in order, the snag ahead of time, and the tip our support team repeats daily.
The short answer
The job: diagnose why your mail gets filtered and rebuild its reputation the right way. Time to set aside: an afternoon. Skill needed: intermediate.
Below are the precise steps, the classic stumble, and one tip from the support desk. Wherever the platform already does a step for you, the guide says so rather than handing you a machine's chores.

On the platform itself
No technical background needed. This walkthrough was written for first-timers, proven on our own hardware, and honest about which parts are genuinely tricky rather than merely unfamiliar.
A promise before step one: nothing here is a one-way door. Any step with teeth is flagged, and the way back is printed beside it.
How the work divides up
Set out end to end, the route is: send a message to a mail-testing service. it scores spf, dkim, dmarc, reverse dns and content in one pass, turning a vague complaint into a checklist you can work through., finish the authentication trio, keep the mail streams apart, look at content and habits and warm up, then keep watching.
Every stage is a few minutes of unhurried clicking — the total depends mostly on how well you already know the control panel. The detailed instructions are further down; read the whole path once before you begin.
Where it comes off, and how to stay on
Complaining about Gmail's fussiness while SPF quietly fails underneath. Most long-running spam-folder cases turn out to be authentication nobody finished, which takes five minutes to diagnose and roughly twenty to fix.
It earns a section of its own because it is no obscure edge case — it is the single commonest reason this task reaches a support queue. Knowing it in advance turns the whole job from risky into routine.
The support desk's own short cut
Ask a few regular contacts to reply once and pull a message out of spam. Recipient behaviour feeds the filters directly, and genuine engagement is the one signal no bulk spammer can fake.
Habits this small are what separate the people who find hosting effortless from the people who find it draining. The same tools on both sides — a different way of working.
The parts that look after themselves here
Steps that never deserved your time are taken out: certificates issue and reissue themselves, the installer handles application setup, the daily copy absorbs the what-ifs, and per-site settings live in a panel rather than a configuration file. The guide covers the remainder — the part that is actually about your site.
Should a step still misfire, support answers at any hour with an actual fix rather than a knowledge-base link and a shrug. Half the guides on this site began as repeat patterns in our ticket queue.

The hosting these steps were tested on
Tutorials written against imaginary hosting go stale fast. Ours are written against the real thing: the same panel, installer and defaults waiting in your account.
Support means a person at any hour, and the remit covers the awkward practical questions other hosts hand straight back.

Why Hosting & Domains
Standard on every plan
The dull parts automated
SSL, backups and installs look after themselves here, leaving the guide to cover only what is genuinely yours.
Jargon never charges you
Every term is defined on the spot or linked to the jargon buster — nothing assumes prior knowledge.
Honest about how big it is
Diagnose why your mail gets filtered and rebuild its reputation the right way is a intermediate-level job — set aside an afternoon, with the platform-absorbed steps marked.
The snag, flagged up front
The classic error for this particular task is named before step one, which is how an afternoon stays an afternoon.
Every undo written out
Any step that could bite is marked, together with the exact way to wind it back.
Works exactly as printed
Every step is proven on the platform we run — none of the 'your host may vary' hedging.
Quick Start
Order placed to site online
- 1
Send a message to a mail-testing service. It scores SPF, DKIM, DMARC, reverse DNS and content in one pass, turning a vague complaint into a checklist you can work through.

- 2
Finish the authentication trio
SPF, DKIM and DMARC, all passing and all aligned with your domain. That tripod sits under every modern filtering decision, and half-done scores the same as not done.
- 3
Keep the mail streams apart
Everyday correspondence through hosting mail; bulk campaigns through a dedicated email service. Forcing newsletter volume down hosting SMTP poisons the reputation both kinds of mail rely on.
- 4
Look at content and habits
Link shorteners, single-image bodies, overselling subject lines and bought lists all trip filters. Content begins to matter once the technical layer is clean, and hardly at all before that.

Warm up, then keep watching
A new domain builds reputation slowly: steady, modest volume to people who genuinely open it. Each big provider's postmaster tools tell you precisely how they rate you at present.

Frequently Asked
The questions that come up most
Why does Gmail junk my mail when Outlook delivers it?
Each provider runs its own filters and holds its own view of your reputation, so one can distrust what another accepts. Complete authentication narrows the gap, and each provider's postmaster tools explain whatever is left.
Does the wording of my emails matter?
At the margins, a little: shorteners, image-only bodies and gimmicky subject lines can tip a borderline score the wrong way. But no rewrite rescues unauthenticated mail, so mend the plumbing before you polish the prose.
What is the uptime commitment, and what happens in a month that misses it?
99.9% — and if a month falls below that through a fault on our side, our terms entitle you to a pro-rated credit; ask and we apply it. Calling it a target rather than a contractual SLA is a deliberate choice. Hardware and network faults surface through platform monitoring, usually before the first customer notices.
Does hosting include mail?
Yes — every hosting plan includes mailboxes at your own name, with webmail, IMAP, POP and SMTP plus spam filtering on from the start. There is standalone email hosting too, for a name whose website lives somewhere else.
