There are several reasons why a contact in your database won't receive your emails, sees a security notice or emails are going to the junk folder. Here are some of the most common issues:
Email sent but not in inbox
Message was blocked by a spam filter
Spam filters consider dozens of factors and assign a "spam score" to each email. If this spam score is higher than a predetermined maximum, the email is moved to the junk folder.
Envoke's sending IP addresses are continually monitored to ensure they are in good standing. We employ feedback loops, automated bounce management and monitor anomalies in email activity.
Despite this ongoing delivery management emails going to spam or junk folders are unavoidable. A surprising number of legitimate emails sent to opt-in lists end up in spam folders. Major Email Service Providers (ESPs) estimate this number is as high as 20%. This is not an Envoke-specific metric - it applies to emails sent from any provider.
Spam filters are different for each server, which means the same email may pass through one spam filter and be flagged by another. They are also "trained" by individuals so spam filtering within the same provider varies by users.
Once the recipient's mail server accepts a message for delivery (there is no failure / bounce recorded) we have no visibility into what decisions that server is making into how to handle it and why.
Here are our suggestions to maximize inbox placement:
- Only send emails to contacts who requested to be emailed and only send content they are subscribed to receive.
- Don't use all images. In fact the text to image ratio in your emails should be high: much more text content than images.
- Including personalization in your email such as merging contacts' first name in the subject line helps in some cases as spam filters are able to verify that you know something about the person you're emailing (this is often not the case with purchased email lists).
- Ask your contacts to add your "from" email address to their safe senders list or address book.
- Ask your contacts to check their custom spam filtering rules that may block your email.
A fraud detection error is shown or the email is blocked internally
If you see a fraud detection or spoofing error notice in your email (usually near the top) chances are it's due to an internal spam filter. Most often this notice is only shown for internal emails and your contacts won't have this issue.
Here are steps you can take to mitigate this issue:
- Authenticate your domain using DKIM (DomainKeys Identified Mail)
- Configuring a custom subdomain can help in resolving the internal delivery issue.
- If the internal delivery issue persists whitelist our sender IPs
Email not sent
Of course none of the troubleshooting steps described above apply if the email was sent in the first place. Ensure that the contact was on the target list, they are subscribed (didn't opt out) and the email campaign was launched (not "in progress", "draft", or "scheduled").
Was the contact on the target list for the message?
Check if the email was on the target list for your email campaign.
No consent (contact is unsubscribed)
Does the contact have a consent status that allows sending emails to them? Contacts need to have express or implied consent so you can send them emails. Unsubscribed contacts or contacts whose consent had expired will not receive emails.
You can view a contact's consent status on the contact details page. Find the contact and click their email address to access the details page.
Tip: If you are testing the unsubscribe link remember to re-subscribe your contact record after you finished testing otherwise your contact record will remain unsubscribed and cannot receive emails.
Has the message been sent already?
Make sure sending is completed by confirming that the status of your campaign is shown as "Sent" on the messages list page.
