Building a fully automated B2B cold outreach system — feasibility, compliance risks, and tool suggestions?
I'm building a fully automated cold outreach system for B2B lead generation and wanted to share my planned stack + get feedback from people who've done something similar and want to know is it possible or not.
The workflow I need to automate:
- Lead gen — Daily find N leads from Apollo using filters (industry, company size, title) → auto-sync to HubSpot
- Send email and linkedIn connection request to 20 people every day.
- If email not replied then follow up email message will be sent.
- Simutaneously send linkedin connection to same person and if connection accepted then follow up till reply by user.
- If we got reply in any of them then sequence will be stopped.

Questions for the community:
- Is this feasible end-to-end? What are the real risks?
- Any compliance landmines (GDPR, CAN-SPAM, CASL) I should be aware of when targeting EU/Canada/UK leads?
- Legal exposure if someone opts out and the system doesn't catch it fast enough?
- Any technical failure points I'm underestimating?
- Platform resistance — how bad is it really?
- LinkedIn: I know they're aggressive about automation detection. What limits are safe? Has anyone been restricted or banned running connection requests at 20/day?
- Email: Deliverability issues with automated sequences? SPF/DKIM/DMARC a must?
- Any tricks to stay under the radar without compromising volume?
- Also suggest tools/other solutions for both automation.
