About SaaSBoost.io (now GTM Works)
SaaSBoost.io rebranded to GTM Works. The copywriting side of the business is different from most “SaaS copywriting agencies” because it’s an extension of a running outbound motion - not a standalone content service.
Every piece of cold email copy, LinkedIn message, follow-up, and sequence variation GTM Works writes has been tested in live Apollo.io campaigns with real reply data. We don’t guess what works. We write, deploy, measure reply rates, and iterate. That feedback loop is what separates cold email copy that actually books meetings from cold email copy that reads well but lands in spam.
Founded by Jeremy Hurley in 2013, the agency brings 20+ years of B2B sales experience (TechTarget sales leadership through IPO, $30M sales org management) to the copywriting work.
Services
Cold email sequence copywriting
- First-touch emails with subject lines, body, and CTAs tested across personas
- Reply-to-thread follow-ups (no subject line, continues the conversation)
- A/B and A/B/C/D/E testing of subject lines and body variations
- Dynamic variable personalization at the persona, account, and contact level
- Spintax and conditional logic for scale without losing specificity
LinkedIn messaging
- Connection request variants (300 char limit, with fallbacks)
- Follow-up messages (Day 3, Day 8 typical cadence)
- Paired with email sequences for multi-channel outreach via HeyReach
Signal-based trigger copy
- Copy tied to specific buyer signals (website visit, job change, funding round, intent data, specific page views)
- Each signal gets a tailored opener that references the signal without being creepy
AI-assisted copywriting via Apollo.io AI Projects
- Custom prompts populated with your ICP, personas, pain points, and messaging guidelines
- Generates first-draft sequences at scale that you review and approve
- Eventually some clients trust the outputs enough to skip approval entirely
Pricing
Copywriting is included in the full outbound management engagement ($999/mo), not billed separately. For copywriting-only projects, hourly consulting ($200/hr) or custom scope.
Who We Work With
B2B SaaS companies and B2B services firms running outbound into defined ICPs. Typical engagements include 3-5 persona variants, 2-3 sequence variants per persona, with ongoing iteration based on reply data.
Example copy work has driven:
- 30+ positive replies/month at Reputation Prime via signal-triggered Reddit-context emails
- $750K+ pipeline at SuccessHACKER
- 7-figure pipeline at Symmetry Corporate Finance
- 10x lead increase at PropelrPay
How We Work With Clients
Most copywriting happens inside Apollo.io AI Projects. We load your ICP, personas, pain points, and value props into the project context, then generate sequence drafts that you review. After approval, we deploy, watch the reply and booking data for 2-3 weeks, and iterate.
Some clients review every send. Others trust us to deploy without approval after the first few cycles. You choose the level of involvement.
