Direct answer
A trailing full stop may be punctuation copied from a sentence, not part of the address. Remove it only after checking the original context, then verify.
More questions and answers
Why do email addresses have angle brackets around them?
Names plus addresses, such as Jane <jane@example.com>, are a normal display format. Extract the address field while retaining the name separately.
Can I clean emails copied from a WhatsApp group?
Extract candidate addresses from the chat export, remove duplicates and validate formatting. Being present in a chat does not imply permission to add people to marketing.
Why does my email list contain mailto: before every address?
The mailto: prefix belongs to a link, not the underlying email address. Strip the prefix during parsing and verify the remaining address.
How do I remove addresses with emojis in them?
Inspect whether the emoji was pasted as surrounding text or is part of an internationalised mailbox format. Use standards-aware parsing instead of deleting every non-ASCII row.
My email list has commas inside names. How do I fix the CSV?
A valid CSV encloses fields containing commas in quotes. Use a proper CSV parser instead of splitting every line on commas; then inspect address columns.
Why do emails from a copied BCC line fail to import?
Recipient lines often contain semicolons, display names and brackets. Parse them into separate address and name columns before verification and import.
Can I clean an email list that has phone numbers mixed in?
Extract strings that plausibly represent email addresses, preserve phone numbers in another field and review ambiguous text. Then run address verification.
Why does my email cleaning tool say my own address is risky?
Some mail servers hide individual mailbox information or temporarily block probes. Check the reported reason; risky does not prove the mailbox is invalid.
Do emails with apostrophes in the username work?
Some address formats permit characters that simplistic validators reject. Do not silently rewrite them; use a standards-aware validator and test compatibility with your sender.
Should I remove email addresses with numbers in the name?
No. Numbers in an email username are common and do not make the address invalid. Judge deliverability from the address and domain, not the name's appearance.
Why are all the emails from one domain marked valid?
A catch-all server may accept any recipient probe. A proper verifier should separate accept-all uncertainty from confirmed mailbox status.
Can I clean a contact list with two people sharing one inbox?
Keep both people as separate contact relationships when necessary, but avoid sending duplicate campaign copies to one address and respect each person's preferences.
How do I remove test@ and example@ from real customer lists?
Flag obvious internal tests or reserved example domains, confirm whether they are production data and maintain a test-account exclusion list. Not every address beginning test@ is necessarily fake.
