Conclusion

Frequently Asked Questions

Yes. You can use modular paragraph blocks, quick research templates, and text-expanders to personalize efficiently. AI tools speed up drafting, but the core system—research, blocks, and tracking—works manually and is highly effective.
Aim for 5–15 minutes depending on priority. High-value roles deserve 10–15 minutes of personalization; backup roles can get 3–5 minutes. Track results and reallocate time to the levels that produce interviews.
Yes—reusing modular blocks is efficient. But always personalize at least one sentence to reference the company or recent news. That single unique detail differentiates your letter from generic reuse.
Automation alone can produce bland output, but when you use tools like Resumize.ai to create drafts and then add one or two company-specific details, the result is both efficient and authentic. Always proofread and include concrete, verifiable achievements.
