Info@ Email Filtering

Invalid addresses bounce because the mailbox does not exist or the domain has no mail server. Role-based addresses reach a real inbox — the issue is that the reader is unknown and the message must work without any personal context.

The distinction matters for how you handle these addresses:

• Invalid means remove permanently. The message cannot be delivered.
• Role-based valid means route to a separate segment with adjusted messaging. The message can be delivered, but it needs to stand on its own without a named recipient.
• Role-based invalid means remove. The shared inbox does not exist.

Deleting all role-based addresses from a local business list often means deleting a third or more of the list — including many deliverable, actively monitored inboxes. Filter by validity and route by type instead.

When to keep a generic inbox vs. when to suppress it.

The decision tree is not "is this address generic?" — it is "is this address deliverable?" Generic addresses pass the same deliverability check as named addresses. The routing decision is separate from the suppression decision.

How BillionVerify's role-based signal helps you segment.

BillionVerify returns a role-based flag alongside the primary validity result. This means you do not need to write prefix-matching logic or maintain a list of generic patterns yourself. The signal tells you two things at once:

1. Whether the address is deliverable
2. Whether the address routes to a shared inbox rather than a named contact

A result of valid + role-based means: this address will accept mail, and it is a generic inbox. Route to your generic-messaging segment.

A result of invalid + role-based means: this address will not accept mail. Suppress it.

A result of valid + not role-based means: this address is a named contact. Route to your main segment.

This combination lets you build routing logic directly from the verification output without inspecting the local part of each email address manually. For large local business lists where role-based addresses can represent 20–40% of all contacts, this signal saves significant cleanup work.

Messaging strategy: generic inboxes vs. named contacts.

The content of your outreach must change when the recipient is a shared inbox. The reader of an info@ address has no context about who you intended to reach. Assumptions you could make with a named contact — their role, their responsibilities, their first name — do not apply.

The most common mistake with generic inbox outreach is applying a first-name personalization template to a role-based address. The result is messages that start with "Hi info," or "Hi contact," — an immediate signal that the sender is not paying attention. Always check that personalization fields fall back gracefully when no first name is available.

Routing table: how to handle each combination.

Catch-all role-based addresses are the highest-uncertainty category. The domain accepts all mail (catch-all) and the inbox is shared (role-based). This means you have no confirmation that the mailbox exists and no named reader. If your campaign economics require high deliverability, exclude this segment entirely. If you have volume to spare, test with a very small batch and watch bounce rates before scaling.

Info@ email filtering common questions.

Handle generic inboxes with the right signal, not a blanket rule.

Generic inboxes are a permanent feature of local business email lists. They are not a problem to eliminate — they are a segment to route correctly. Verify the address, check the role-based flag, and send messaging that works for a shared inbox. BillionVerify gives you the signal you need to make that decision at scale.
