Most Congested
The keyword is dominated by GMass with 400K users and a 4.8 rating, creating a steep competitive gap.
Mailmeteor follows at 50K users, also at 4.8.
A generic competitor at 10K users scores only 2.7, showing quality differentiation is critical for traction.
Possible Openings
Email tracking keywords like 'Email Tracking Gmail' (14.8K), 'Gmail Email Tracker' (14.3K), and 'Email Tracking In Gmail' (14.1K) offer adjacent opportunities with similar search demand but likely fewer focused extensions.

The generic 'Mail Merge for Gmail' at 2.7 confirms users penalize poor execution heavily.
