Your emails land in spam folders. Your calls go unanswered. That's not just bad luck—it's a sign your sender reputation needs work. With solid email authentication using SPF, DKIM, and DMARC, plus clean mailing lists and sharp monitoring of engagement rates, your messages can finally reach the right inboxes. We'll also cover how branded calling and proper number registration boost your caller reputation, making sure your SMS and MMS campaigns get noticed too.
Sender reputation is the score that internet service providers (ISPs) assign to organizations that send emails. This score determines whether your emails reach inboxes or get filtered as spam. Similar concepts apply to phone calls and text messages.
Email sender reputation relies on multiple factors. First, email authentication protocols verify you are who you claim to be:
SPF (Sender Policy Framework) - Authorizes which IP addresses can send emails from your domain
DKIM (DomainKeys Identified Mail) - Adds a digital signature to verify emails haven't been tampered with
DMARC (Domain-based Message Authentication, Reporting & Conformance) - Sets policies for handling emails that fail authentication
Proper implementation of these protocols signals to ISPs that you're a legitimate sender, improving email deliverability.
A clean mailing list is essential for good sender reputation. This means:
Removing invalid addresses
Respecting unsubscribe requests promptly
Segmenting your audience for relevant content
Using double opt-in for new subscribers
When recipients engage positively with your emails, ISPs notice and improve your sender score.
Tracking how recipients interact with your emails provides valuable insights:
Open rates
Click-through rates
Reply rates
Spam complaints
Low engagement rates can hurt your sender reputation. Regular monitoring allows you to adjust strategies before deliverability suffers.
Just as email has sender reputation, phone calls have caller reputation systems.
Proper registration of your business phone numbers is becoming mandatory:
Registering with Third Party services like Hiya and TransUnion
Providing accurate business information
Keeping registration current
Unregistered numbers face increased blocking and flagging as potential spam.
Branded calling enhances trust when making outbound calls:
Displays your business name on caller ID
Can show your logo on supporting devices
May include reason for calling
This transparency increases answer rates dramatically compared to unknown numbers.
Text messaging campaigns require similar reputation management:
Register with wireless carriers
Maintain consent records
Keep message frequency reasonable
Provide clear opt-out instructions
Proper registration ensures your SMS and MMS messages reach their intended recipients instead of being blocked as spam.
