Instantly.ai has grown rapidly by solving the biggest problem in cold email — deliverability at scale. Its core value is infrastructure: connect unlimited email accounts, warm them up automatically, rotate sending across accounts, and monitor deliverability metrics. The AI email writing feature exists but is secondary to the sending engine.

Infrastructure vs. Content

Instantly’s selling point is not its email writer — it is the ability to send thousands of cold emails per day without landing in spam. The platform handles domain rotation, warm-up schedules, send-rate limiting, and bounce management. Txtory does none of that. It writes email text. The two tools sit at opposite ends of the cold email pipeline: Txtory produces the words, Instantly delivers them.

The Lead Database

Instantly includes a B2B lead database with over 160 million contacts, complete with email verification. That means you can find leads, write sequences, and send — all without leaving the platform. Txtory has no lead data. If you already have your prospect list, this does not matter. If you need to build one, Instantly’s database is a significant time saver.

The Bottom Line

Instantly is for teams that need cold email sending infrastructure at scale. Txtory is for anyone who needs cold email copy written well and fast. Use both: write with Txtory, send with Instantly.

What makes Instantly different from Lemlist?
Instantly focuses on sending volume and deliverability — unlimited email accounts, aggressive warm-up, and simple sequences. Lemlist offers more multichannel features (LinkedIn, calls) and deeper personalization. Instantly is optimized for scale; Lemlist for sophistication.
Can Txtory replace Instantly's email writing?
For the writing part, yes. Txtory generates cold email text that you can paste into Instantly's sequence builder. Instantly's built-in AI is convenient but not the main reason people use the platform.
Why do cold emailers need multiple mailboxes?
Sending hundreds of emails from one mailbox triggers spam filters and damages your domain reputation. Instantly lets you connect unlimited email accounts and rotates sending across them, keeping each account within safe sending limits.
Is $30/month cheap for cold email infrastructure?
Very. Instantly's pricing is aggressive compared to competitors. The Growth plan at $30/month includes unlimited email accounts, warm-up, and 5,000 emails per month. For B2B sales teams, that is a fraction of the value one closed deal generates.
Do I need Instantly if I only send a few cold emails?
No. For low-volume outreach (under 50 emails per month), send from your regular email. Generate the text with Txtory. You only need Instantly when volume requires infrastructure.
