As holiday party season approaches, event planners, businesses, and individuals alike rely heavily on digital invitations and electronic greeting cards. Unfortunately, cybercriminals are well aware of this seasonal trend and frequently use fake e-cards and party invites as phishing lures to trick unsuspecting recipients into clicking malicious links.
Check Before You Click
If you receive an unexpected email asking you to click a link to view a holiday party invitation or e-card, pause before taking action. Always verify the request with the supposed sender using a trusted alternate communication channel—such as a quick phone call, direct text, or separate chat message—to confirm that the message is authentic.
Why Legitimate Invitations Look Suspicious to Spam Filters
To deliver messages that appear personalized, many third-party event platforms send emails “on your behalf.” In doing so, these services often spoof your domain or email address to make the invitation look like it originated directly from your mailbox.
Because hackers use this exact same spoofing technique to execute phishing attacks, modern email security systems and spam filters block unauthorized spoofed messages by default. Without proper domain authentication, your legitimate event invitations and greeting cards risk landing directly in your guests’ spam folders—or being blocked entirely.
How to Send Business Invitations Safely
If your organization uses third-party event, marketing, or greeting card tools to send email on your behalf, proper technical configuration is essential to ensure high deliverability and guard against cyber threats.
The team at Pegasus Technologies can configure your business domain to recognize authorized third-party senders using three critical email authentication protocols:
- SPF (Sender Policy Framework): Defines a specific list of mail servers and IP addresses that are authorized to send email on behalf of your domain.
- DKIM (DomainKeys Identified Mail): Appends an encrypted digital signature to outgoing messages, proving to receiving mail servers that the email was not altered in transit.
- DMARC (Domain-based Message Authentication, Reporting, and Conformance): Provides explicit instructions to receiving servers on how to handle emails that fail SPF or DKIM checks (e.g., monitor, quarantine, or reject).
Important Security Tip: Before uploading your corporate or customer contact lists to any third-party invitation platform, make sure to review their security standards and privacy policies to protect your proprietary data.
