You have now written an email with AI-generated content.
Rephrase Email Language
With the rephrase option, Apollo's AI rewrites sections of your email based on the guidance you provide, such as making text shorter, breaking text into bullet points, or simplifying the language used. You can use AI to edit the emails you write yourself or to adjust AI-generated content.
To use the rephrase option when you write an email:
- Highlight a phrase, sentence, or paragraph in your email and click Rephrase.

- Review the generated messaging. If you like the changes, click Insert text to replace the selected text directly in the email draft. You can also regenerate the text if you want to consider a different option.
You have now rephrased an email with Apollo AI.
Analyze Emails to Improve Messaging
If you're not sure whether an email is good enough to send, use Apollo's AI email analyzer to rate your emails for reading time, reading level, clarity, and structure. This helps ensure that you optimize your emails for engagement and send messages that your prospects want to open and read.
To analyze emails before you send them, click Analyze. You should strive for a score of 90+ to increase your reply rate.
If Apollo's email analyzer marks an email as not ready to send, review each suggestion and implement the advice. Then, click Refresh score.
Use Personalized Email Openers
Personalization is a key component of successful email messaging. When you enable AI-generated personalized openers for emails, Apollo tailors the opener of each message to the specific events or information most relevant to each contact. This helps grab their attention, build rapport, and increase the likelihood of a response while significantly reducing your research time.
Depending on the data available for a contact, there are several types of personalized openers that Apollo generates:
- Company mission: Speak to contacts on their level with openers tailored to their core company goals and values.
- Current role: Meet contacts where they are at with openers that relate to their current position within a company.
- Upcoming anniversary: Build rapport by anticipating upcoming milestones.
- Job focus: Tailor the start of your message to the specific areas that contacts care most about.
- Solution focus: Focus on resolving your recipient's pain points.
- Work history: Mention your recipient's past work experience.
- Work anniversary: Show you've done your research with timely openers that touch on a recent anniversary.
If you've set up signals, Apollo also generates signal-based openers for individual emails.
You can generate and use personalized openers for both individual emails and emails in a sequence.
To add personalized openers to an individual email:
- Launch Apollo and click People.
- Select a contact, then click their email address.
- Click Generate > Email opener.
- Apollo generates several email openers. Click Copy beside the opener you want to use, then paste the text into your email.

You how have used the AI assistant to generate a personalized email opener.
To add personalized openers to emails in your sequence:
- Launch Apollo and click Sequences.
- Select a sequence, then click an email step.
- Click Insert AI variable > Personalize email with AI.
- Toggle Use personalized openers, and Apollo automatically generates email openers based on information like work anniversaries or company mission. Click to preview an available opener.

- When personalized openers are enabled, Apollo automatically chooses between potential openers based on the data available for each contact added to the sequence. Apollo creates tasks for you to review and approve the AI-generated email message.
- To review potential openers, select a contact, then generate a preview. If an option is greyed out, Apollo doesn't have the necessary opener to generate that preview.
- If Apollo doesn't have enough data to generate a personalized opener for a contact, or if your company reaches its AI word limit, you can choose to send the email with a generic opener or pause the sequence instead. However, you should avoid sending too many generic emails if you want to avoid spam filters.
You have now used the AI assistant on emails in a sequence.
The Apollo AI writing assistant only supports English.
Track Your AI Word Usage
Your Apollo plan determines how many words you can generate with the AI writing assistant. Check out Apollo plans for specific word counts by plan. All the words generated by Apollo AI per user count towards your monthly limit. This includes all the words in the email copy and personalized opener options that Apollo generates for you. Unused AI words don't roll over from one monthly billing cycle to the next, so make sure your team takes advantage of Apollo AI from the start of each billing cycle.
Want to increase the number of words your team can generate per month? Click Request Upgrade from the AI history settings in Apollo.
To track the number of AI words you and your team use:
- Launch Apollo and click Settings > Billing and credits > Credits & AI usage > AI Word Usage.
- Apollo shares how many AI words your team has generated within the current billing cycle, as well as the date when the word count will reset.
- The AI word usage history section also shows the number of AI words generated per user in your team and the date they were generated. Use the filters to review AI use by specific date ranges and users.
Apollo has a daily rate limit of 50 email generations per user per 24 hours. If you reach the daily limit, you can resume sending the following day.
