Create effective email content
Formatting issues, unusual links, or attachments can trigger spam filters. Pay attention to the following best practices when writing emails.
Message format
Use a standards compliant email client that supports both HTML and plain text versions.
Keep layouts simple and avoid overly complex designs with many images.
Avoid invisible tracking tools or active components. Link to rich content on your website instead.
Links
Only include links to reputable websites.
Do not use IP addresses or shortened URLs. Always use a clear domain name.
Word choice
Use personalised greetings and natural language.
Avoid excessive punctuation, capital letters, and common spam terms.
Do not include statements claiming the email is not spam.
Avoid references to typical spam related topics such as medications, financial schemes, or explicit content.
Attachments
Use clear and simple file names if attachments are necessary.
Prefer cloud services such as Microsoft OneDrive or Google Drive to share files via links.
Avoid attachments whenever possible as they can increase spam detection.
Tip: Following these best practices consistently helps improve email deliverability and reduces the likelihood of temporary sending restrictions.

Frequently asked questions
Why was my email address blocked?
In most cases, an email address is blocked automatically for security reasons. This helps protect your email account and the email system, for example in case of unusual sending behavior or potential misuse.
The block remains in place until it is reviewed and, if applicable, lifted by the Jimdo Support team. The exact reason can only be determined by support during this review.
Can I unblock my email address myself?
No. The unblock can only be performed by the Jimdo Support team and always requires an individual review.
Will incoming emails still work if my address is blocked?
Yes. In most cases, only outgoing emails are affected. You can still receive emails.
How can I avoid future email blocks?
Keep a consistent sending pattern and follow the recommended limits. For larger volumes of emails, use specialised external providers.
I already contacted support. Do I need to do anything else?
No. If you are already in contact with support, no further action is required. Do not reply again to the same request and wait for a response in your existing ticket.
