Emails land in spam
Customers miss invoices, confirmations and business correspondence. You need to understand what may be triggering filters.
Emails not arriving?Let’s find out why.
We diagnose delivery problems in Google Workspace / Gmail and Microsoft 365 / Outlook. We check your domain and sending configuration, agree on fixes and check the results again.

SCROLL / DECODE
WHEN TO GET HELP
Sent does not always mean received.
For businesses whose important emails go missing, bounce back or are accepted inconsistently by Gmail and Outlook.
Some emails never arrive
Bounce rates are high. You see delays, rejections or delivery error messages.
Your sending setup has changed
Problems started after a domain setup or a change of sending system. Or you need SPF / DKIM / DMARC checked before making changes.
Our core systems
- Google Workspace / Gmail
- Microsoft 365 / Outlook
WHAT WE CHECK
Your domain, sender and delivery errors.
We compare your configuration with sample messages and available provider data. Support for other ESPs and SMTP platforms must be confirmed separately before work begins.
SPF: who can send
We check the DNS record that specifies which servers may send email on behalf of your domain.
DKIM: the message signature
We check how messages are signed and whether the recipient can validate the signature, helping confirm the sender and message integrity.
DMARC: authentication rules
We check whether SPF / DKIM align with the domain in the From field, and review the policy for messages that fail authentication.
DNS and sending configuration
We review authentication records and available sending settings for errors and inconsistencies.
Reputation signals
We examine available domain and sender reputation signals, including Google or Microsoft data where available for your setup.
Bounces and spam placement
We review message headers, bounce messages, error codes and available logs to identify likely causes of delivery problems.
AFTER DIAGNOSIS
From findings to checked changes.
01
Issues and priorities
You receive a list of identified issues, an explanation of their impact and a recommended order for fixes.
02
Agree and implement fixes
We agree on the scope and make changes within the available configuration and granted permissions.
03
Recheck and hand over
We recheck settings and available signals after the changes, then give your team the findings and recommendations.
ACCESS
The access your task needs.
- DNS and domain settings.
- Google Workspace Admin or Microsoft 365 Admin, depending on your system.
- Sending platform settings and available logs.
- Sample messages with headers, bounce messages and delivery errors.
We agree on access for your specific task. Wherever possible, we use delegated access with appropriate permissions; sharing ordinary passwords is not our standard access method.
WHAT YOU RECEIVE
Clear findings for your team.
- A prioritised issue list with an explanation of the causes.
- A record of agreed fixes and follow-up check results.
- Operating recommendations and remaining limitations.
OSNOVA does not guarantee that every email will reach the inbox. Results also depend on Google, Microsoft, receiving providers, domain history and sending behaviour. We do not guarantee a reputation score, blacklist removal or the lifting of third-party provider restrictions.
EMAIL / START
Start with diagnosis.
Tell us which emails are missing and which system you use to send them. Pricing is estimated individually by scope; fixes are quoted after diagnosis. We agree on timing after assessing the task.
