Write Emails with AI
The writing assistant only supports English.
Apollo limits each person to fifty AI email generations per 24 hours. All words generated by Apollo AI count toward your monthly AI word usage limit, including email copy and personalized openers. Your Apollo plan determines your total monthly AI word usage limit. Unused words don't roll over between billing cycles. You can view your team's total usage, reset date, and per-user breakdown in Settings > Billing and credits > Credits & AI usage. If you use AI research in AI-generated emails, each email incurs credit usage.
You can use the AI writing assistant to write an email to a single prospect or to write emails in a sequence:

You have now rephrased text with Apollo AI.
Analyze Emails to Improve Messaging
You can only use the AI writing assistant to analyze emails you write to individual contacts — not emails you write on sequences.
If you're unsure whether an email is good enough to send, use Apollo AI to rate it for reading time, reading level, clarity, and structure. This helps you optimize your messaging for engagement so you only send messages that your prospects want to open and read.
To analyze emails before you send them:
- Click Analyze after writing your email to an individual contact.
- Apollo analyzes your email and returns an overall score along with a detected tone and custom suggestions for improvement.
You should strive for a score of 90%+ to increase your reply rate.
If email analysis marks your email as not ready to send, review each suggestion and implement the advice, then click Refresh score.
You have now used the writing assistant to analyze your email.
Troubleshoot the Writing Assistant
If you generate email content with the writing assistant, but it only shows the variable in brackets like {{example_email}} with no generated text to review, check out the following troubleshooting steps:
AI generation is still in progress: If you're creating AI openers in a sequence, Apollo generates them asynchronously in the background. While generation is in progress, drafts and tasks may temporarily display only the AI variable like {{example_email_opener}} instead of the final text. Wait 1 to 2 minutes, then open the email directly from the sequence or associated task. Opening the email often triggers AI content to render on your browser.
Insufficient credits or AI word usage available: If your team doesn't have enough credits or AI words available when the emails are created or scheduled, the AI opener isn't generated by Apollo. To resolve this issue, add credits to your account or manage your plan to raise your monthly AI word limit. Then check whether the opener generates automatically. You can also reduce the number of contacts in the sequence to align with the credits and AI word usage currently available.
