Many companies use an extra layer of security on top of their regular email provider (ESP). These are called Secure Email Gateways (SEGs)—email security solutions such as Barracuda, Mimecast, Proofpoint, and Cisco.
SEGs filter, block, or quarantine emails before they ever reach the recipient’s inbox. Because of this, reaching these inboxes is more difficult, which can reduce deliverability and make outreach less effective.
Why It Matters
By identifying SEGs early, you can:
Avoid sending to hard-to-reach leads.
Protect your domain reputation and inbox placement.
Focus your campaigns on contacts that are more likely to receive, open, and respond to your emails.
How Instantly Helps
Instantly automatically detects and flags contacts protected by Secure Email Gateways (SEGs) as soon as you upload email addresses to a list or campaign.
You can view this information in your campaign’s Leads table.
The Email Security Gateway column is located toward the right side of the Leads table. Scroll horizontally to the right to view these columns.
