GeminiWe run Instantly for real clients, not just in theory.
Most Instantly trainings are run by people who read the docs the night before. At Hack'celeration it's the opposite: inbox setup, warmup, sequences that get replies, rotation and lead finder, that's our daily agency work. Everything we teach you, we practice on campaigns that are live. We know the traps (the inbox sent into the fire with no warmup, the main domain burned to save a few days) because we've already solved them.
- We run Instantly cold email for real clients every week, not just in theory
- 1-on-1 format: the trainer adapts to your level, beginner or seasoned sales rep
- We tell you when Instantly isn't the right call (sometimes Lemlist or Smartlead fit your case better)
- We start from your real account and your actual lists, not a dummy example
Four pillars so your cold email lands and books.
A badly configured Instantly means burned inboxes, emails in spam, zero replies. Most of the trouble comes from the setup and the warmup, not the tool. We pick up your real account and work through the four pillars together.
- Inbox setup and warmup
Your inboxes ready, warmed up before the first send
We connect your inboxes (secondary domains, Google Workspace, Microsoft 365), set SPF, DKIM and DMARC, then launch Instantly's native warmup. Since Gmail and Yahoo tightened their sender rules in 2024, sending from a fresh inbox with no warmup means straight to spam. We warm up for 2 to 3 weeks before a single cold email goes out.
Fix my inbox setup - Campaigns and sequences
Sequences that get replies, not unsubscribes
We build your campaigns: personalization variables (first name, company, custom opener), spintax to vary every send, spaced follow-ups, stop-on-reply conditions. We write the angle, A/B test subject lines, set sending windows. The goal isn't to send more, it's to book meetings.
See the sequences - Deliverability and rotation
Your emails in the inbox, thanks to inbox rotation
Instantly spreads your sends across multiple mailboxes (inbox rotation) so you never burn a domain. We watch your reputation, cap the volume per mailbox per day, keep warmup running alongside campaigns. We check your spam rates with a placement test and adjust before things slip.
See deliverability - Lead finder, CRM and integrations
Plug Instantly into your lead finder and your CRM
We use the built-in lead finder (a B2B database of millions of contacts) to build your lists, verify emails and filter by industry, size, title. Then we connect Instantly to your CRM and to Make or n8n through the API and webhooks: a positive reply creates a deal, a booked meeting logs itself. The Instantly CRM handles the pipeline if you don't have one.

- A diagnosis of your setup (inboxes, warmup, domains, sequences)
- The first fixes to make, in priority order
- The right 1-on-1 format for your level and send volume
- An honest take: Instantly or another tool for your case
Your Instantly program, step by step.
Five steps, no skipping. Each one on your real account, with a clear deliverable. From the first session we go after what's blocking your deliverability. By the end, you run your campaigns and your deliverability without us.
- Step 1 · Account audit
We open your real Instantly account and spot what's broken
First session, we share your screen and look at your account together. Are your sending domains authenticated? Are your inboxes warmed up, or are you sending cold? What do your sequences look like, and what's your reply rate? We list the real reasons your emails hit spam or nobody replies. You leave with a clear diagnosis and the list of fixes, in priority order. No theory, your real account.
- Step 2 · Inbox setup and warmup
Inboxes connected, SPF, DKIM, DMARC set, warmup running
We tackle the foundation: deliverability starts before the first send. We connect your inboxes on secondary domains to protect your main domain, configure SPF, DKIM and DMARC, verify authentication. Then we turn on Instantly's native warmup and let it run for 2 to 3 weeks. We also set the sending limits per mailbox per day. By the end, your inboxes are ready to send cold email without burning your domain.
- Step 3 · Campaigns and sequences
Lists, sequences and A/B on your real prospects
We build your campaigns. First the lists: built-in lead finder to target by industry, size and title, then email verification to avoid bounces. Then the sequences: personalized opener, spintax to vary every send, spaced follow-ups, stop on reply. We A/B test subject lines and set sending windows. You practice on your own prospects, not a dummy example.
- Step 4 · Deliverability and automation
We wire up rotation, the CRM and Make or n8n
This is where Instantly holds over time. We turn on inbox rotation to spread sends across multiple mailboxes, run a placement test to see if you're hitting spam, adjust the volumes. Then we connect Instantly to your CRM and to n8n or Make through the API and webhooks: a positive reply creates a deal, a meeting logs itself, a follow-up fires on the right trigger. We track your real numbers in a dashboard.
- Step 5 · Autonomy
You run your campaigns and your deliverability without us
The number one goal: you become autonomous. By the end of the program, you know how to connect an inbox, warm it up, write a sequence, read your reply rates and hold your deliverability with rotation. You no longer need an agency to run your cold email. And if you want to delegate later, we also run an Instantly agency, but that's not the point here.

The questions we get the most.
What is a 1-on-1 Instantly training?
An individual program with an Instantly expert, not a class of 100 people. We open your real account, look at your setup, and work through your actual cases: inbox and warmup, sequences, deliverability, lead finder. You ask your questions live, the trainer adapts the pace to your level. We schedule sessions around your availability, and you leave with concrete actions every time. That's what makes the difference on a topic as tricky as cold email.How much does the Instantly training cost?
There is no single price. We connect you with a trainer certified by Hack'celeration, matched to your need and your level. It varies from one trainer to another, based on their profile and the format that fits your project.Instantly or Lemlist: which one to pick?
It depends on your need. Instantly is built for volume: unlimited inboxes, native warmup, inbox rotation and a built-in lead finder, all at an aggressive price. Lemlist leans more on deep personalization (dynamic images, videos) and multichannel LinkedIn. If you want to scale cold email with many mailboxes and solid deliverability, Instantly is strong. If your angle is hyper-personalization at low volume, look at Lemlist. During the training, we help you decide based on your real case.Can Instantly be integrated with Make or n8n?
Yes, and it's one of the parts of the training. Instantly exposes an API and webhooks that connect to Make and n8n. You can trigger actions on any event: a positive reply creates a deal in your CRM, an interested lead drops into a list, a booked meeting logs into your calendar. We build full workflows together so your cold email talks to your CRM and your stack without manual copy-paste. No code required.Do I need to be technical to take the Instantly training?
No, not necessarily. Instantly has a visual interface to connect your inboxes, run warmup and build your sequences. The slightly technical part is the DNS config (SPF, DKIM, DMARC) to authenticate your domains, and the 1-on-1 format is built exactly for that: we set it up together, screen shared. Beginner, we go step by step. Seasoned rep, we jump straight to sequences and rotation. And you can automate through Make or n8n without ever touching code.What is Instantly warmup for?
Warmup heats up your inboxes before you send cold email. Instantly automatically exchanges emails between thousands of accounts in the network: your messages get opened, marked as important, pulled out of spam. It builds your sender reputation gradually so that when you send your real campaigns, your emails reach the inbox. We keep warmup running alongside the sends. With no warmup on a fresh inbox, you go almost straight to spam, especially since Gmail and Yahoo's 2024 rules.How does Instantly help cold email deliverability?
On several levers. Inbox rotation spreads your sends across multiple mailboxes so you never burn a single domain. Native warmup keeps your reputation up. We cap the volume per mailbox per day, authenticate every domain (SPF, DKIM, DMARC), and run a placement test to see if you're hitting spam before sending to your whole list. Cold email deliverability is 80% setup and discipline, not magic. We show you how to hold it over time.How good is the Instantly lead finder?
Instantly bundles a B2B database of several million contacts right inside the tool. You filter by industry, company size, title, region, you verify emails to limit bounces, and you export straight into a campaign without a third-party tool. It's handy to start fast and keep everything in one place. Quality depends on the niche: on some specialized markets a dedicated source is still better. In training, we show you how to build clean lists and when to top up with another source.How many inboxes do I need to start on Instantly?
It depends on your target volume. A good rule: don't exceed 30 to 50 cold emails per mailbox per day to stay under the filters' radar. If you aim for 300 sends a day, count 6 to 10 inboxes spread across 2 or 3 secondary domains. Instantly allows unlimited inboxes on most plans, so you scale without paying per mailbox. We size your setup together based on your goal, and we warm up each mailbox before sending it into the fire.Is the training online or in person?
100% online, over video, 1-on-1. You join the sessions from anywhere, we share your screen and your Instantly account live. Sessions are recorded if you want to revisit them. The individual format means real interaction: you're not a number in a webinar of 100, the trainer answers your questions about your setup. That's what makes learning concrete on a tool as deliverability-driven as Instantly.
