Emails from System One end up in spam folders
There are two scenarios.
- Emails where System One is the sender, e.g. user credentials, advancing requests, etc.
- Emails where the user is the sender, e.g. emails sent from shows, contracts and invoices.
When you have problems with emails where the user is the sender, make sure your domain is authenticated.
It can happen that emails end up in spam folders. We've taken a number of measures to make sure that this happens as little as possible. First some general info.
How do spam filters work?
A filtering solution applied to the email system uses a set of protocols to determine which of your incoming messages are spam and which are not. There are several different types of spam filters available:
- Content filters – review the content within a message to determine whether or not it is spam
- Header filters – review the email header in search of falsified information
- General blacklist filters – stop all emails that come from a blacklisted file of known spammers
- Rules-based filters – use user-defined criteria – such as specific senders or specific wording in the subject line or body – to block spam
- Permission filters – require anyone sending a message to be pre-approved by the recipient
- Challenge-response filters – require anyone sending a message to enter a code in order to gain permission to send email
Spam filtering solutions are commonly deployed in two ways: as hosted / “cloud” or as software installed on the users' computers that integrate with an email client such as Microsoft Outlook.
What does System One do to avoid being marked as spam?
We take a number of measures to make sure that emails sent from System One don't end up in SPAM folders.
- Quality email server: All emails sent from System One are sent through a premium email delivery service (SendGrid.com). They have a good online reputation and therefore mails have a better chance of being accepted by spam solutions. They also make sure the emails that are being sent have the correct headers.
- Correct configuration: We have configured our DNS records to meet SPF and DKIM requirements.
What can you do to avoid being marked as spam?
- Don't send bulk email: If you want to send an email to a large group of people, System One might not be the right solution. Have a look at Mailchimp for instance.
- Avoid certain words/phrases: Content filters might be triggered by words or phrases that are very common to spam emails.
- Avoid overly rich footers: When you have a lot of images in the signature of your email, the email might be classified as a newsletter.
What if your email ends up in a spam folder?
There are many different spam filtering solutions, configured by many different system administrators who can all make up their own filter rules. It will happen that your email ends up sometimes in a spam folder.
If this consistently happens with a specific recipient, please ask them to check why this is happening with their system administrator .
We are happy to receive a report from their system administrator, if they believe there is something we can improve!Related articles:
