Preparation
1. MX and SPF must be set
MX: To improve the arrival rate of mail, some recipients will check whether there is any configuration. If the MX for receiving mail has been configured, the Direct Mail MX can be deleted.
SPF: prevents others from maliciously registering the same sending account on the Direct Mail platform to send notifications and promotion information under false names.
2. It is recommended to set DKIM and DMARC. With these email anti-counterfeiting measures, the credibility of the email will be higher and the email arrival rate can be improved.
DKIM: In the Direct Mail console, find the configuration information of the corresponding domain name in the Email Domains and obtain the record value. Reference: What Is DKIM? How to Setup DKIM Records?
It is an email security protocol that verifies the email sending domain name through message encryption and authentication to check whether the email has been tampered with during transmission to ensure the integrity of the email body.
DMARC: Users do not need to apply for DMARC. Please check What is DMARC and How to Configure DMARC Records?
It can prevent others from forging your domain name. You can also obtain information about attempts by others to forge your domain name. When the recipient (whose MTA must support the DMARC protocol) receives the email sent from the domain, DMARC verification will be performed. If the verification fails, a report will be sent to the email address set by DMARC.
3. Provide true and effective unsubscribe links
The unsubscribe service generally grows in the user system. Each time when user sends an email, it contains a special unsubscribe link that contains the recipient's email. When the customer clicks this link, the request goes to your unsubscribe service, and the recipient you resolved will be removed from your emailing address. Unsubscribing link or unsubscribing is handled by the sender.
4. Follow the recommendations of the test website to improve the quality of emails
You can use this website to test, send email body to the test mailbox, and check whether it will be considered spam. (Note: This website is also a reference. The anti-spam system of each mail service provider is different, but it can help improve your body quality.)
5. Add the sender address to whitelist in advance
If the recipient is from the same company, you can contact the recipient's email administrator to add your sending address to the whitelist.
6. Apply to the recipient in advance.
If you are sending a newsletter care email or notification letter to your own members, you can consult the email service provider of recipient in advance.
Sending Suggestions
1. The high frequency of bursts may easily lead to the flow control of the receiver. It is recommended that the user warm-up at first, gradually increase the amount of emails, and extend the time to evenly send emails. For more information, please check Warm up.
2. Ensure that the recipient list is of high quality, that is, it contains active users who have agreed to receive your emails. Clean up invalid addresses in a timely manner. If the invalid address rate is too high, the system's downgrade and blocking rules will be triggered.
3. It is recommended not to frequently send emails with the same subject to multiple recipients of the same email service provider at the same time, which may also be automatically judged as spam by the system.
