Why do my emails end up in spam?
There are many reasons why email providers might mark your emails as spam. Here are the most common causes we have come across and how you can resolve them.
Sending from a public domain
If you send messages from a free domain such as gmail.com, yahoo.com and so on, your emails are very likely to end up in the spam folder.
To ensure better deliverability, make sure you send your emails from a domain you own that matches your brand.
DMARC
If the domain you use to send emails has a DMARC policy but you have not verified it with your SMTP provider, your messages will probably end up in spam.
Contact your SMTP provider for instructions on how to make sure the messages sent from Futuria CRM pass the DMARC checks.
Contact list quality and how you collect it
Once all the technical aspects have been sorted, the quality of your contact list and the way you collect it are the most important factors for deliverability. Make sure that:
- Everyone on your list has given explicit consent to receive your marketing emails.
- Inactive subscribers are removed from your list regularly.
- Your sign-up forms are protected with double opt-in.
Sending internal emails
Are you sending messages to the same domain the email comes from? For example, from info@tuodominio.com to mario@tuodominio.com. In this case, it is common for these internal messages to end up in spam.
This happens because your inbox receives a message that appears to come from itself, but it knows it did not send it (Futuria CRM did). The inbox therefore assumes this is a spoofing attempt and moves the message to spam.
If you are only sending internal emails to run tests, we recommend using a free email address (e.g. Gmail). If, on the other hand, you need to send internal emails regularly, ask whoever manages your domain's email to whitelist the IP address of your SMTP provider.
Sending volume or frequency issues
Email providers monitor the frequency and the volume of the emails you send. A sudden spike in sending volume can be read as a warning signal.
How to fix it:
- Warm up your sending domain by gradually increasing the volume over time.
- Keep a consistent sending schedule.
- Avoid long periods of inactivity followed by mass sends.
Content that triggers spam filters
Even if your domain authentication is correct, the content of the email itself can trigger spam filters.
Elements that can cause problems:
- Excessive use of promotional words (e.g. "Free", "Limited offer", "Act now").
- Too many images with very little text.
- Use of link shorteners (such as bit.ly).
- Large attachments or attachments in unsupported formats.
How to fix it:
- Write in a clear, conversational tone.
- Get the balance between images and text right.
- Always use direct links to your website instead of link shorteners.
Frequently asked questions (FAQ)
How can I check whether my emails will end up in spam before I send them to my list?
You can use email testing tools that analyse the content and the sender's reputation. It is also good practice to send test emails to several providers (such as Gmail, Outlook and so on) to see where they are delivered.
What can I do if my domain has a poor sender reputation?
Improving your domain's reputation takes several strategies. Increase your sending volume gradually, clean your contact list regularly and engage actively with your audience to increase open rates.
How often should I clean my email list to avoid spam problems?
We recommend cleaning your email list every 6 to 12 months. Regularly remove inactive subscribers and anyone who has not engaged with your emails, to keep the list healthy and improve deliverability.
