Email Allowlist
Never Miss Important Emails from VIP Contacts
Create an email allowlist to ensure important emails always reach your inbox. Email Ferret allowlist prevents false positives and ensures VIP senders, key clients, and trusted domains are never blocked.
How Does Email Allowlist Work?
VIP Protection
Add important senders, domains, or email addresses to your allowlist. Emails from allowlisted senders always reach your inbox, regardless of spam scoring.
Flexible Options
Add individual email addresses, entire domains, or specific senders. Allowlist entries take effect immediately and apply to all future emails.
Prevent False Positives
Allowlist prevents legitimate emails from being flagged as spam. If a legitimate email is flagged, simply add the sender to your allowlist to prevent future false positives.
An Allowlist Is Insurance, Not Configuration
Any filter makes two kinds of mistake, and they do not cost the same. Letting one cold email through costs you the two seconds it takes to archive it. Filing one real message under the wrong label can cost you a client, an offer, or a deadline — and you will not notice it happened, because the failure mode of a false positive is silence.
That asymmetry is why Email Ferret is tuned to let borderline mail through rather than flag it. But tuning is a general answer, and your inbox has specific senders whose mail you cannot afford to miss even once. The allowlist is how you name them.
Which means an allowlist is not something you configure once and forget. It is the small set of senders where you have decided the filter should not get a vote — and a set that small is worth keeping deliberate.
How to Build an Allowlist You Can Trust
Seed it on purpose, correct it as you go, and prune it before it goes stale.
Start with the senders you cannot afford to miss
Before you look at anything that was flagged, seed the list deliberately: your accountant, your lawyer, your kid’s school, the domain your biggest client sends from. These are the senders where one missed message costs real money or real trust, and none of them need to be flagged first to be worth adding.
Add your own domains and your team’s
Internal mail should never be scored as outreach. Adding your company domain and any domain you own covers colleagues, alerts, and the automated mail your own systems send you — a category that looks surprisingly machine-generated to a filter reading behavior.
Allowlist from flagged mail as you go
When something you wanted turns up under a label, add that sender from the message itself. This is the routine correction, and it is the one that shapes the list to your actual mail rather than to what you guessed in advance.
Prune it once a quarter
An allowlist is a standing exception, and exceptions outlive their reason. The vendor you evaluated last year and the recruiter from a search that closed are now guaranteed inbox access for a relationship that ended. Ten minutes a quarter keeps the list meaning what it says.
Who Belongs on an Allowlist
Worth adding
- Professional services. Your accountant, lawyer, doctor, or broker — infrequent senders whose mail is always time-sensitive when it does arrive.
- Client and partner domains. New people join those companies and email you for the first time; a domain entry covers the ones you have not met yet.
- Your own domains. Internal mail and system notifications should never be scored as outreach.
- Schools, landlords, government. Mail that is genuinely unsolicited, genuinely templated, and genuinely unmissable.
Think twice
- Free mail providers. Allowlisting an entire consumer email domain waves through everyone who can register a free address, which is everyone.
- Vendors mid-evaluation. Useful while you are actually evaluating. A permanent inbox pass once you are not.
- Anything you added to stop one annoyance. An entry added in irritation outlives the irritation. This is what the quarterly prune is for.
- Large shared platforms. A domain that sends for thousands of businesses is not a sender you can vouch for.
