Frequently Asked Questions

What makes an AI tool the best email generator?

The best email generator combines high-quality, on-brand copy with practical features: personalization tokens, templates, bulk generation, and integrations. Deliverability aids (subject line scoring, spam checks) and originality tools like a paraphraser or plagiarism checker are also important.
