Is an email address with a dot before the @ symbol valid for Gmail?

Email marketer from Reddit comments that Gmail often allows invalid email addresses, but this can vary. They don't recommend relying on this behavior, as it could change. It's best to validate email addresses properly before using them, even for Gmail.

Marketer from Email Geeks states that technically local.@domain.com is invalid according to RFC and should be assumed as such everywhere. Even if some email apps or SMTP servers allow it. He also adds that even though Google may accept it at their MX (mail exchanger), it doesn't mean it will get there via other MTAs (Mail Transfer Agents) and Google also doesn't deem it valid in their own apps, so you should assume it's invalid.

Email marketer from Email Hippo warns that while some providers are flexible, addresses must conform to generally accepted formats. Addresses like “email.@example.com” are flagged as invalid.

Email marketer from Debounce includes addresses with a dot right before the @ (e.g., “name.@example.com”) in the category of syntactically incorrect email addresses.

Email marketer from NeverBounce identifies addresses with a dot immediately preceding the @ symbol (e.g., “john.doe.@example.com”) as an invalid email format, leading to deliverability issues.

Email marketer from Google Support states that Gmail ignores periods in Gmail addresses. While they do not explicitly address the case of a period directly before the @ symbol, the general principle of ignoring periods suggests it might be treated as valid.

Email marketer from Stack Overflow reports that while the RFC might say that a dot right before the @ symbol is invalid, it's likely that Gmail will still deliver the email to the correct address, even though it's technically wrong.

Email marketer from Kickbox advises that, while Gmail might be lenient, standard email address syntax should be adhered to. They imply that a dot right before the @ would be considered non-standard.

Expert from Email Geeks received an email at an address with a dot right before the @ symbol. She explains that Gmail accepts the email, but your ESP may block such addresses because they are invalid SMTP. Even if the ESP accepts it the SMTP may put quotes around it. She says the fact direct emails are accepted into gmail does not mean other providers will work. She recommends treating those addresses as invalid if you were a client.

Expert from Word to the Wise does not directly address whether a dot before the @ sign in an email is valid. They mainly focus on general deliverability issues and list management rather than email address syntax.

Expert from Email Geeks tested sending an email to aliversonchicago.@gmail.com from Yahoo to Gmail and it delivered successfully to aliversonchicago@gmail.com. This suggests Gmail's UI checks might differ from inbound mail processing and Gmail accepts email addresses with a dot before the @ symbol.

Expert from Spam Resource does not explicitly address the specific scenario of a dot right before the @ symbol. It generally states that email addresses must follow proper syntax to be valid and deliverable but doesn't provide enough info to determine either way.

Documentation from MSDN notes that in general, the local part of an email address has specific restrictions regarding periods. It does not list that this is acceptable in email addresses.

Documentation from Mailgun's Flanker library indicates that dots at the beginning or end of the local part are not permitted. While this doesn't explicitly address dots immediately before the @, it implies that it would likely be considered invalid.

Documentation from RFC Editor specifies that while periods are allowed in the local part of an email address, they cannot be the first or last character, nor can they appear consecutively. Therefore, an address with a dot immediately before the @ symbol is technically invalid according to RFC 5322.
