Why Emails Go to Spam

Spam filters analyse your sending reputation, authentication records, and email content. Missing any of these can cause your campaigns to land in spam instead of the inbox.

Email Authentication (DNS Records)

• SPF - Tells email providers which servers are authorised to send on behalf of your domain.
• DKIM - Adds a cryptographic signature to verify email authenticity.
• DMARC - Instructs providers on how to handle emails that fail SPF or DKIM checks.

Set these up in your domain DNS settings. VoVo provides the exact records you need under Communications > Settings > Email Authentication.

Content Best Practices

• Avoid ALL CAPS and excessive exclamation marks.
• Do not use spammy phrases like FREE, ACT NOW, or GUARANTEED.
• Maintain a good text-to-image ratio - do not send image-only emails.
• Include a plain-text version of your email.
• Always include a visible unsubscribe link (added automatically).

List Hygiene

Regularly remove hard-bounced addresses and inactive subscribers. High bounce rates damage your sender reputation and can cause your entire domain to be blacklisted.
