Check your list before a Gmail™ mail merge

Gmail™ mail merge sends what your sheet says — including the mistakes. Pre-flight Check reads your list and your @tags, finds the broken fields, blank names, dupes and typos, and shows you every email before Gmail™ sends it.

• @tags matched Gmail™'s way — including the first-tab rule.
• Headers Gmail™ can't address, flagged with the @A fallback.
• Quota against Gmail™'s daily limit (verified date stated, never promised).
• A Ready to send tab, offered a move to first position.
