We set up a mailing system with send mail node for my client and it works properly but sometimes my client cannot send the mail and a message returns and mail involves SPAM:
My client tried to send it through the mail clients’ own page -IONOS- and he says this message can be send from there and they say when they send out through Send Mail Node, it sends this as a SPAM.
What might be the problem in here? Is this about Send Mail Node?
Information on your n8n setup
- n8n version:Version 0.219.0
- Database (default: SQLite):
- n8n EXECUTIONS_PROCESS setting (default):
- Running n8n via (npm):
- Operating system: Linux
I believe the issue is more with the SMTP provider you’re using.
Not related to Send Email Node.
I believe so too but I need to prove this to my client. Why do you think this could be the reason?
Well. Domain Reputation + Email Provider.
There could be many reasons.
- Flagged IP Address
- Might be sending bulk emails
- Previous emails marked as spam
Since this is not related to n8n I can’t help much on this.
Hey @mcnaveen ,
Thank you, you gave me some good answers.
Then please tell me why it cannot be related to n8n?
N8n just gives a platform/node to have your credentials and use them to send emails.
FYI, I have been using Send Email Node for the Past 3 Years and I never faced this issue.
What I suggest is to change the email sending domain, This is a general suggestion and not related to n8n.
You can use this tool to check the email spam score of your domain name. https://www.mail-tester.com/
Since this topic is going out of context, I’m not gonna reply further.
Thanks for your understanding.
Hey @mcnaveen ,
These helped me a lot.
I prepared a defense of n8n againist the claims of spam situations, for n8n developers’ use:
Defense for n8n regarding the spam email issue:
Based on the provided conversation and what is known about n8n or similar mail client platforms, we can defend that the issue of emails being marked as spam is not directly related to n8n itself. Here are the reasons to support this defense:
Functionality of n8n: n8n is an open-source workflow automation tool that provides a Send Email node to send emails using SMTP (Simple Mail Transfer Protocol). Its primary purpose is to enable users to send emails using their specified email credentials and configurations. It does not alter the content or characteristics of the emails being sent.
Email Content: n8n does not have control over the content of the emails being sent. The content, including the subject, body, and attachments, is determined by the user or the data in the workflow. If an email is marked as spam, it is more likely due to the content and not the means of sending it through n8n.
Reputation and Email Provider: As mentioned in the conversation, the reputation of the domain and the email provider play a significant role in email deliverability. If the email provider (SMTP server) used by n8n has a poor reputation due to past spam activities or other issues, it could affect email deliverability.
Domain Authentication: Proper domain authentication (e.g., SPF, DKIM, DMARC) is crucial for preventing emails from being marked as spam. This authentication process occurs at the domain level and is independent of n8n. Users need to set up these records correctly for their domain to enhance email deliverability.
Email Volume and Content: As mentioned, sending bulk emails or having a history of emails marked as spam could trigger spam filters. While n8n can be used to automate bulk email sending, it is essential to ensure that the email content is not perceived as spammy or misleading.
Email Service Provider Policies: Email service providers, including SMTP providers, have their own policies and spam filters. If the provider has strict spam detection mechanisms, certain emails may be flagged regardless of the platform used to send them.
Mail-Tester Score: Using tools like Mail-Tester (https://www.mail-tester.com/) can help identify potential issues with email deliverability, including spam score and domain reputation. It’s a good practice to test emails before sending them in bulk.
In conclusion, n8n provides the tools and platform to send emails but does not control the deliverability or spam marking of those emails. The issue is more likely related to the email provider, domain reputation, email content, or other external factors. Addressing these aspects, along with understanding the email provider’s policies, can help improve email deliverability and prevent emails from being marked as spam.
Cool, Thanks for updating!
