Common Mistakes (And What To Do Instead)
Mistake: Choosing a platform based only on price
The real cost is not the subscription. It is wasted cycles from a tool that does not match your workflow. Start by deciding your channel strategy: email-only or multichannel.
Mistake: Scaling mailboxes before messaging works
If you do not have a repeatable offer and a tested ICP, more mailboxes just amplify noise. Aim for consistent positive replies first, then scale volume.
Mistake: Treating deliverability as a one-time setup
Warm-up, domain reputation, and list hygiene are ongoing. Build a weekly routine and watch reply rates and spam signals.
FAQ
Which tool is best for founders?
If you want to keep it simple, Instantly is usually the fastest path to sending. If you need LinkedIn steps and better reporting, Reply.io is a better long-term system.
Do I need multichannel?
Not always. Email can work great if your ICP is clear and your offer is tight. Multichannel helps when email gets crowded or when you need higher reply rates with fewer leads.
Can I start with one tool and switch later?
Yes. Many teams start with Instantly for speed, then move to Reply.io when they need more process and multichannel. Switching is easier if you keep your lead sources and CRM clean.
