Automatic Candidate Follow-up Emails: Personalized Communication at Scale

Learn how to automatically generate personalized interview invitations, rejection emails, and follow-up messages based on screening results. Maintain candidate experience while eliminating manual communication work.

Quick CLI Example
# Generate interview email for top candidate
hiresquire email \
  --job 123 \
  --candidate 456 \
  --type invite \
  --tone friendly

Why Automated Candidate Emails?

Automated follow-up emails solve critical hiring pain points:

  • Consistent experience: Every candidate receives timely, professional communication
  • Zero manual work: Eliminate hours of repetitive email writing
  • Personalization: AI-generated emails tailored to each candidate's score and strengths
  • Brand consistency: Maintain your company voice across all communications
  • Scalability: Handle 100s of candidates without increasing headcount

Available Email Types

Type Use Case Trigger (Suggested)
invite Invite top candidates to interview Score 80-100
keep-warm Keep candidate engaged for future roles Score 60-79
followup Generic follow-up for more info Manual / Agent Choice
rejection Standard rejection email Score < 60

CLI Workflow

Generate emails directly from the command line after your screening finishes:

# 1. Submit screening
hiresquire screen --title "Senior Dev" --description "..." --resumes ./resumes/ --watch

# 2. Get top candidates (score > 80)
hiresquire results --job 123 --min-score 80 --json

# 3. Generate invite for the best match
hiresquire email --job 123 --candidate 456 --type invite --tone friendly

Python SDK Integration

Automate email generation in your custom Python workflows:

from hiresquire import HireSquire

client = HireSquire("your_token")

# After screening completes
results = client.wait_for_completion(job_id)

for candidate in results["candidates"]:
    # Determine email type based on score
    if candidate["score"] >= 80:
        email_type = "invite"
    elif candidate["score"] >= 60:
        email_type = "keep-warm"
    else:
        email_type = "rejection"
    
    # Generate personalized email
    email = client.candidates.generate_email(
        job_id=job_id,
        candidate_id=candidate["id"],
        email_type=email_type,
        tone="professional",
        custom_notes=f"Your strengths in {', '.join(candidate['raw_analysis']['strengths'][:2])} stood out."
    )
    
    # Process or send the email
    print(f"Subject: {email['subject']}")
    print(f"Body: {email['body']}")

REST API Endpoint

With HireSquire, you can generate personalized emails directly via the API. This is perfect for integration into existing systems or low-code tools like n8n and Zapier.

Step 1: Generate an Interview Invite

Once you've identified a top candidate, use the generate-email endpoint:

# POST /api/v1/jobs/{job_id}/generate-email
{
  "candidate_id": 456,
  "type": "invite",
  "tone": "friendly",
  "custom_notes": "We loved your experience with Laravel and AWS."
}

Step 2: Keep-Warm and Follow-ups

Don't let candidates go cold while you're still reviewing others. Use the keep-warm type to stay in touch:

# POST /api/v1/jobs/{job_id}/generate-email
{
  "candidate_id": 456,
  "type": "keep-warm",
  "tone": "professional"
}

Zapier Automation Workflow

Set up completely automated email workflows with Zapier:

Best Practices

Candidate Experience Guidelines
