Email deliverability best practices

Authentication

Gmail, Yahoo and Outlook require bulk senders to authenticate their domain. XaaS Techs sets up SPF, DKIM and DMARC records so mailbox providers can verify your emails are genuine.

List health

• Only email people who opted in or are customers
• Remove bounced and invalid addresses promptly
• Re-engage or remove contacts who have not opened in a long time
• Never buy or rent email lists

Content

• Use a clear, honest subject line
• Keep a good balance of text and images, and avoid all-caps and excessive punctuation
• Include your business name and mailing address
• Always include a working one-click unsubscribe link

Sending habits

• Send on a consistent schedule
• Avoid sudden huge spikes in volume
• Watch complaint rates. If people mark your email as spam, adjust content and frequency
