Our pick
Lavender scores your email as you type inside Gmail or Outlook, suggests specific improvements, and predicts how likely it is to get a reply. It also shows prospect and company context in a sidebar.
How we chose
This tool went through independent editorial research and platform evaluation, drawing on vendor documentation, published pricing and aggregated user reviews. Every score uses the same four published factors: core job performance, price against alternatives, day-to-day reliability, and value for the person most likely to buy it.
Scores are never for sale, and affiliate relationships do not affect them.
Questions
Does Lavender send emails for me?
No. It coaches the emails you write, inside Gmail or Outlook. For bulk sending, pair it with a sequencing tool.
Is there a free plan?
Yes. The free plan analyses a limited number of emails per month, and paid plans start at $29/month.
