Teams wanting sending and a lead database in one platform
Instantly is commonly used by outbound teams as an alternative to Smartlead for multi-inbox sending — the core workflow (rotation, warm-up, deliverability monitoring) is similar between the two.
As with any volume sending platform, it's more than a small, low-volume campaign needs — a simpler setup is usually enough when you're not sending from a large inbox pool.
Pricing changes frequently — check Instantly's website for current plans.
We've settled on Smartlead and PlusVibe as our own standing sending infrastructure, so we don't have a hands-on comparison to offer on Instantly specifically — it's a well-known name in the same category and worth knowing about if you're evaluating sending platforms.
