Step 01
Get your AI API key
Top Reacher uses AI to write unique personalised paragraphs for every contact. You choose your provider and bring your own key. Groq is completely free and works well under 30 emails per day. For higher volumes, OpenAI's GPT-4o-mini is the recommended choice.

Step 02
Set up smtp2go so emails send from your real address
Top Reacher sends through smtp2go so every email arrives from your real Gmail or Outlook address, not a bulk platform. This is why deliverability is flawless, no shared IPs, no promotions tab, no spam folder.

Step 03
Upload your contact list
Go to Contacts and upload a CSV or Excel file. You need owner name, business name, and email as a minimum. Adding a website column is optional but strongly recommended, Top Reacher fetches each site before writing, which is the single biggest factor in how specific and convincing the personalisation is.

Step 04
Set up inbox rotation to scale your daily volume
Add multiple sender addresses and Top Reacher automatically rotates between them, round-robin or random. Each inbox stays under its safe daily send limit while your total volume scales up to 1,250 emails per day. Every inbox is verified through smtp2go so deliverability stays flawless across all of them.

Step 05
Write your email template once
Write your base email in Mail Template. Use merge fields like {{owner_name}} for contact details and drop in AI instruction blocks for the sections you want personalised. Add a randomised subject line so every email looks hand-written. You write it once, Top Reacher executes it differently for every single contact.

Step 06
Configure your session to stay out of spam
Before sending, set your delay between emails and your session batch limit. A delay of 1–3 minutes between sends looks human to spam filters. The session limit caps how many go out in one sitting across all inboxes. These two controls, combined with inbox rotation, are why Top Reacher emails land in the inbox every time.

Hi Rohan, I came across BrandCo's work helping D2C brands build identity systems that actually convert, particularly the Zara India case study on your site. I will keep this brief. Most brand agencies I speak with tell me their biggest challenge is converting warm leads into retainers. For studios focused on identity work, the bottleneck is usually outreach volume, not quality, and that is exactly where Top Reacher fits.

Hi Sarah, Flowdesk's approach to automating customer onboarding for SaaS teams caught my attention, the live chat routing feature in your product walkthrough is genuinely clever. SaaS teams at your stage often find that outbound is the fastest path to early ARR targets...
