How many emails can YAMM send per day?

Gmail free accounts have a 500/day limit; Google Workspace accounts allow 2,000/day. Exceeding this requires batch sending or plan upgrades.

How does YAMM track email performance?

YAMM logs opens, clicks, replies, and bounces for each email directly in Google Sheets, updating in real-time without switching platforms.

Are placeholders case-sensitive?

Depends on the tool. Some mail merge tools are case-sensitive. Ensure placeholders in your template exactly match Google Sheets column names to avoid merge errors.

Does YAMM support custom attachments?

Yes. You can auto-attach different files per recipient based on their data—e.g., personalized invoices or reports—saving manual work.

Decision Guidance

Use YAMM if: You're on Google Workspace, need to send personalized emails (sales outreach, event invites, newsletters), prefer working in Gmail, and value deliverability and real-time tracking. Ideal for small to mid-sized teams and budget-conscious marketers.
