Frequently asked questions
What is email list cleaning?
Email list cleaning is the process of removing addresses that will hurt your sending: invalid or misspelled emails, hard bounces, disposable addresses, role accounts, and risky catch-alls. You validate each address, drop or flag the bad ones, and keep a list that actually reaches inboxes.
How often should you clean your email list?
Clean before every major send, and set a cadence based on how fast your list grows and ages. Most senders do a full clean every three to six months, plus a real-time check at signup so the list stays clean between passes. High-volume or older lists need it more often.
What is email scrubbing?
Email scrubbing is another term for email list cleaning: scrubbing a list means running it against validation checks and stripping out the addresses that would bounce, sit in a spam trap, or drag down your reputation. The goal is a list where almost every address is real and reachable.
What gets removed when you clean a list?
A clean removes invalid and misformatted addresses, hard bounces, disposable and temporary domains, role-based addresses like info@ or support@, and often risky catch-all domains. Typo suggestions catch fixable mistakes such as gmial.com, so you recover real subscribers instead of dropping them.
Does list cleaning improve deliverability?
Yes, indirectly. Bounces and spam-trap hits are what damage sender reputation, and reputation is what mailbox providers use to decide inbox versus spam. Removing the addresses that cause those hits protects your reputation, which in turn protects deliverability. It cannot fix bad content or poor engagement on its own.
What is the difference between list cleaning and email verification?
Email verification checks a single address, usually at the point of entry like a signup form. List cleaning applies that same verification across an entire existing list in bulk. Verification keeps new addresses clean going in; cleaning fixes the list you already have.
Can you clean an email list in bulk?
Yes. You can clean a list at scale by running each address through Abstract's Email Validation API and keeping only the ones that pass. Many teams do a one-time bulk pass on their existing list, then validate at signup so it never gets dirty again.
