Instantly

What it does

Instantly handles the unglamorous half of outbound — domain warm-up, inbox rotation, sending limits and bounce monitoring — so a small team can send at volume without burning its main domain in the first week.

It sends; it does not decide who should receive what. List quality and the offer are still yours, and they matter more than the tool.

Standout features

• Domain and inbox warm-up
• Sending limits and rotation
• Bounce and deliverability monitoring
• Reply detection and sequencing

Main job: run cold email volume safely with warm-up, throttling and deliverability visibility.

Best for

Use it when you have a narrow, verified prospect list and need the sending infrastructure to stay out of spam folders.

Getting started

Set up separate sending domains, warm them for two to three weeks, then start with a small daily cap and watch bounce and reply rates before raising it. Keep the primary company domain out of the rotation.

Watch out for

Watch out: a new domain blasting thousands of mails gets filtered within days, and lookalike domains damage the brand. Check unsubscribe and GDPR obligations for every market you mail into.
