Sending Guide

Outgoing DNS Records

• You need to configure outgoing DNS records before sending emails. Otherwise, your emails will most likely go to the recipient’s spam folder or be bounced directly.
• Outgoing DNS records are different from incoming DNS records. Click to view: Outgoing DNS setup guide. If you do not know how to configure them, you can contact customer support for remote setup Click to view: Customer support help

  

Sending Limits

• GetMX Domain-Email is for work use only. To ensure normal users’ email deliverability, please do not send the following types of emails. If detected by the system, your sending function will be restricted and no refund will be issued. If you use email for marketing purposes, please look for a dedicated marketing email service provider.
  • Marketing or advertising emails
  • Illegal emails involving pornography, violence, etc.
  • Verification codes
  • Bulk sending the same content to multiple external mailboxes
• Free users have sent large volumes of illegal advertisements, causing serious abuse and affecting normal users. Sending is therefore no longer supported for Free users.
• A single email can be up to 25 MB. Most email platforms, including Gmail, currently limit incoming emails to 25 MB; emails exceeding this size may be rejected or bounced. If you need to transfer large files, try using cloud storage to prevent the recipient from rejecting or bouncing the email.

Multi-Channel Sending

For sending external emails, multi-channel sending is supported. If one server fails to send or is rejected by the recipient, the system will try sending through another server.

• Internal emails (the recipient also uses GetMX and is not using a Scale mailbox): Sent through the internal channel and can arrive in seconds.
• External emails (Scale or recipients who are not using GetMX): Multi-channel email sending can be configured.

FAQ

Why can’t my mailbox send emails?

The following two conditions must be met. Please check them in order.

• Paid version
• Outgoing DNS records have been configured in the backend where the domain was purchased. Outgoing DNS records are different from incoming DNS records and must be configured separately.

Why do the emails I send go to the recipient’s spam folder?

Whether an email goes to spam depends on the recipient’s policies. You can check the following items:

1. Sent email content
   • Spam marketing emails
   • Test emails (simple numbers or a string of letters are easily classified as spam)
2. Domain
   • If outgoing DNS records have just been configured, do not send emails immediately. Wait a few hours for the recipient to recognize the records. If the recipient has not recognized the records, sent emails may go to spam.
   • The domain is classified as a risky domain by the recipient.
3. Sending server
   • The GetMX admin console supports multiple sending regions. The same region is more likely to be accepted by the recipient.

How to troubleshoot a sending failure prompt

1. Check the sending status in the admin console
2. View sending logs https://www.getmx.com
3. Sending too many test emails may cause them to go to spam. It is best to ask the recipient to whitelist the mailbox.
4. Sending attachments larger than 25 MB may result in rejection or sending failure.
