# Template sequence library with A/B testing

Build campaigns from a library of reusable email sequences, and A/B test variants to find what converts.

Every campaign shouldn't start from scratch. The sequences that work — the ones with the right pacing, the right number of steps, the right follow-up angles for your market — are worth saving, reusing, and testing against each other. The sequence library makes that possible, and A/B testing at the step level makes it systematic.

## Reuse what works

The new sequence library lets you save and reuse complete email sequences across campaigns instead of rebuilding them each time. Combine it with A/B testing to find which variant converts, then roll the winner forward into future campaigns.

Template sequence library with A/B testing

Template library with industry-specific sequences

## How to use it

1. In a template campaign's **Workflow** tab, click **Template** to open the library.
2. **Browse** proven sequences by industry — B2B SaaS, e-commerce, energy, and more — or start from **Custom** if you're building from scratch.
3. Apply a sequence and tailor the copy to your specific offer, audience, and call to action.
4. Create variants of any sequence step. FirstSales splits sends between the variants so you can compare reply rates and keep the winner.

## Why rebuilding every campaign is expensive

Most outreach teams spend the same hour rebuilding the same five-step sequence every time they launch a campaign. Change the ICP, update the offer, adjust the angle — but the scaffold is fundamentally the same. That repeated work adds up fast, and it introduces inconsistency: sequences built in a hurry before a campaign launch often have subtle structural problems that only become apparent weeks later in the reply rate data.

The library eliminates that rework. Apply a structure that's already laid out and tuned for your industry, then focus your effort on the copy rather than the scaffolding. The starting points aren't generic outlines — they're organized by industry, which matters because sequence structure isn't one-size-fits-all. A B2B SaaS sequence benefits from different pacing and follow-up angles than an e-commerce or energy campaign. Starting from a relevant template means your timing, step count, and follow-up logic are already in the right ballpark before you write a single word of copy.

## A/B testing built in

Variant testing at the step level lets you answer the questions that matter for reply rate: does a shorter opener outperform a longer one? Does a soft close beat a direct ask on the third follow-up? Does leading with a case study beat leading with a question? Rather than guessing based on intuition, you send both versions and let real reply data decide — then carry the winning structure into your next campaign as the new baseline. Over time, the sequences your team uses get measurably sharper, shaped by what your specific audience actually responds to rather than what felt right in the moment.
