Pros and cons
What Instantly does especially well — and the limits to anticipate.
Pros

Cons
- No permanent free tier.
- Pointless outside cold prospecting.
- Billing rises with volume.
Instantly: when it makes sense.
Instantly makes sense for cold outbound at volume with many inboxes; for a newsletter or transactional email, another type of tool fits better.
Keep if
You run cold email prospecting at volume.. You want to warm up and manage multiple sending inboxes.
Challenge if
You don't do cold email.. You want a simple newsletter tool.
