A/B Test Sequence with Variants

This sequence is for SDR Managers, Heads of Growth, and RevOps leaders who are past the initial 'does this work?' phase and are now focused on optimization. Use this framework when you have a baseline that works but need to find a new angle or improve reply rates on a proven campaign.

This isn't for finding product-market fit; it's for systematically improving performance on campaigns sending over 10k emails per month.

This is a disciplined, email-only sequence designed to produce a clear winner between two distinct approaches. Adding other channels like LinkedIn introduces too many variables and clouds the results.

1. Steps: 6 (including internal analysis)
2. Duration: 16 days
3. Channels: Email only

A/B testing requires controlled personalization. The goal is to test a scalable message, not to write 2,000 unique emails. Personalization should be limited to standardized fields like {{first_name}}, {{company_name}}, and {{title}}.

The variable you are testing—the core pain point, the offer, the CTA—must remain consistent across all emails within its variant group. Over-personalizing introduces noise that makes it impossible to know why one variant outperformed the other.

A/B testing isn't a copywriting problem; it's an infrastructure problem. To get a statistically significant result, you need to send at least 1,000 emails per variant. Sending 2,000+ emails from a single inbox in a short period will destroy its reputation and land you in spam, invalidating your test results.

This is where infrastructure becomes non-negotiable:

1. Inbox Rotation: To send 2,000 emails safely, you need to spread the volume across 40-50 warmed-up inboxes (sending ~30-50 emails each per day). Manually orchestrating this is an operational nightmare.
2. Dedicated Domains: Run your tests on dedicated sending domains, completely separate from your primary corporate domain. If a test variant performs poorly and gets high spam complaints, it won't damage the deliverability of your main domain used for customer and investor communication.

For Heads of Growth and RevOps, using a primary domain for high-volume testing is a critical error. Once your main domain (yourcompany.com) is flagged by Google or Microsoft, all communications—from marketing newsletters to sales contracts—are at risk. This is why mature outbound teams isolate sending operations on separate, dedicated infrastructure.

Tools like SuperSend exist to handle this infra and orchestration so teams don't have to duct-tape it together. We manage the domain rotation, inbox warmup, and volume balancing automatically, letting you focus on the test itself, not the plumbing.
