Using Apollo’s Database

Building Prospect Lists

Search Filters:

Example: Find VP-level sales contacts at B2B SaaS companies

Person Filters:
  - Title: VP, Vice President, Director
  - Department: Sales, Revenue, Business Development
  - Seniority: VP, Director

Company Filters:
  - Industry: Software, SaaS
  - Employee Count: 50-500
  - Technologies: Salesforce, HubSpot (indicates B2B)
  - Location: United States

Results: Save as list

Saved Searches:

Create saved searches for ongoing prospecting:

1. Build your filter criteria
2. Click Save Search
3. Enable notifications for new matches
4. Apollo alerts you when new contacts match

Chrome Extension Prospecting

On LinkedIn:

1. Visit a profile
2. Click Apollo extension
3. See contact info (email, phone)
4. Add to list or sequence with one click

Best practices:

• Verify emails before adding to sequences
• Don’t scrape entire company pages (violates LinkedIn ToS)
• Use for targeted, intentional prospecting

Enriching Existing Data

From CRM:

1. Apollo pulls contacts from Salesforce/HubSpot
2. Automatically enriches with Apollo data
3. Pushes enriched data back

From CSV:

1. Data → Import
2. Upload your list
3. Apollo enriches matching records
4. Export or push to CRM

Sequences (Email Automation)

Creating a Sequence

1. Go to Engage → Sequences
2. Click New Sequence
3. Configure steps:

Example: Initial Outreach Sequence

Step 1: Email (Day 1)
  Subject: {first_name}, quick question about {company}
  Body: [Personalized first email]

Step 2: Email (Day 3)
  Subject: Re: {first_name}, quick question about {company}
  Body: [Follow-up, different angle]

Step 3: LinkedIn Task (Day 5)
  Action: Send connection request

Step 4: Email (Day 7)
  Subject: [New subject line]
  Body: [Case study or social proof]

Step 5: Call Task (Day 10)
  Action: Call if phone available

Step 6: Email (Day 14)
  Subject: Should I close your file?
  Body: [Breakup email]

Sequence Best Practices

Email Limits:

• Start with 30-50 emails/day per inbox
• Gradually increase over 2-3 weeks
• Watch bounce rates and spam complaints

Personalization:

• Use Apollo’s variables: {first_name}, {company}, {title}
• Add custom fields for deeper personalization
• Consider Clay for AI-generated personalization

Timing:

• Send during business hours (recipient’s timezone)
• Tuesday-Thursday typically best
• Avoid Mondays and Fridays

Replies:

• Apollo auto-detects replies
• Responders exit the sequence
• Out-of-office triggers pause (configurable)

Sequence + CRM Workflow

Apollo Sequence Flow:

1. Add contact to sequence in Apollo
   ↓
2. Apollo sends emails
   ↓
3. Apollo logs activities to Salesforce/HubSpot
   ↓
4. Contact replies
   ↓
5. Apollo stops sequence
   ↓
6. Task created in CRM for rep follow-up
   ↓
7. Rep takes over conversation

Enrichment Workflows

Real-Time Enrichment

When saving contacts:

1. Apollo automatically enriches on save
2. Fills in missing fields
3. Verifies email
4. Pushes to CRM

Bulk Enrichment

For existing data:

1. Export from CRM (or upload CSV)
2. Import to Apollo
3. Apollo enriches matching records
4. Export or push back to CRM

Enrichment Coverage

Apollo’s coverage varies:

Segment	Email Coverage	Phone Coverage
US Tech	65-75%	40-50%

US SMB	50-60%	30-40%
