  1. Open the Email Scheduler → Schedule tab

    In the campaign builder, click the Email Scheduler step and stay on the Schedule tab (the other tabs are Senders and Recipients). This is where sending time and days are set.

  2. Understand smart scheduling

    Read the callout at the top: “Smart scheduling automatically determines optimal send times based on recipient timezone, engagement history and available sender slots.” You set the guardrails on this tab (timezone and days) not the exact minute a message goes out.

  3. Set the Campaign Timezone

    Search and pick a Campaign Timezone from the picker. It's the fallback timezone used only when a contact's own timezone is unknown, so emails still land during business hours in that zone.

  4. Choose sending days

    Under Sending days, toggle days on or off: it defaults to Monday through Friday. This applies across every email step in the campaign, including follow-ups.

    Choose sending days

  5. Leave timezone blank for auto-detect

    If you don't set a timezone, it falls back to auto-detect or UTC. Setting an explicit timezone is safer when you know your audience's region.

  6. Save

    The schedule governs all steps in the campaign. Combine it with per-mailbox sending limits to control overall volume alongside timing.

Pro tips

  • Timezone is a fallback, not an override

    A contact's own known timezone always wins. The Campaign Timezone only fills the gap when a contact's timezone is unknown.

  • Weekdays-only is the safe default

    Weekend sends can dent reply and spam metrics for B2B outreach: the Mon–Fri default exists for a reason.

  • There's no manual send-throttle here

    Pacing within business hours is automatic via smart scheduling. Control overall volume through per-mailbox daily limits instead.

  • Set the timezone to your buyers, not your office

    Business hours are computed in whichever timezone you pick: choose the one your prospects actually work in.

Frequently asked questions

Does the campaign timezone override each contact's timezone?

No: it's a fallback. A contact's own timezone is used when known; the Campaign Timezone only applies when it isn't.

What are the default sending days?

Monday through Friday.

Can I set an exact send time?

No. Smart scheduling picks send times automatically based on recipient timezone, engagement history, and available sender slots.

Why don't I see a daily send-limit field here?

Sending pace is automatic on this tab. Volume limits are configured per mailbox, not per campaign schedule.

What happens if I leave the timezone empty?

It falls back to auto-detect, or UTC if that can't be determined.

Do sending days apply to follow-up steps too?

Yes: the Sending days setting applies across every email step in the campaign, not just the first.

Can I send on weekends?

Yes: toggle Saturday and/or Sunday on under Sending days if your audience is active on weekends.

Your coding agent sets up the FirstSales CLI and skills for you.

Prompt for Claude Code

I'm setting up FirstSales (https://firstsales.io), an AI outbound sales platform: campaigns, contacts, a reply inbox, deliverability and lead signals. Help me get my workspace sending real, good emails end to end, from Claude Code.

Read these first so you know how FirstSales works:
- Developer docs and API: https://developer.firstsales.io
- CLI: https://www.npmjs.com/package/@firstsales.io/cli
- Skills for coding agents: https://github.com/firstsalesio/firstsales-skills (read README.md and GUIDE.md)

Setup
1. Install the CLI: npm install -g @firstsales.io/cli
2. Install the FirstSales skills:
   claude plugin marketplace add firstsalesio/firstsales-skills
   claude plugin install firstsales@firstsales
3. Ask me if I already have a FirstSales account. If not, send me to https://app.firstsales.io to sign up.
4. Ask me to create an API key under Settings → API → API Keys, with only the scopes we need.
   Never ask me to paste the key into this chat. Tell me to run this in my own terminal, so the key stays hidden:
   read -rs FS_KEY && firstsales auth login --api-key "$FS_KEY"; unset FS_KEY
5. Run `firstsales whoami` and tell me which workspace and organisation we are connected to.

Then ask me about my business: what I sell, who I sell to (roles, company size, countries), my best customers, and what I use today for outbound (tools, lists, mailboxes). Walk me through:
1. Teaching FirstSales my business: website, offer, proof points and case studies in the knowledge base, so the AI writes like someone who knows the product.
2. Connecting my sending mailboxes and checking my sending domain: SPF, DKIM, DMARC and warm-up. If anything is unhealthy, tell me the exact DNS record to add.
3. Bringing in contacts: import my CSV or CRM export into a clean list, remove duplicates and bad emails, and block domains I must never email (customers, competitors, my own).
4. Building my first campaign: the right list, senders, steps and timing. Write the sequence with me, show me the drafts, and do not launch until I say yes.
5. Setting up Signals if it fits: find people engaging with LinkedIn posts about topics my buyers care about, and turn them into leads.
6. Inviting my team and giving each person the right access.

Once campaigns run, show me how to work the reply inbox from here: which replies need an answer, draft responses in my voice, and move good conversations into deals. If I use Cal.com, connect it so follow-ups can offer my booking link (not the first email).

Throughout, as you learn about my business, proactively suggest and help create:
- Reply templates for the questions and objections my prospects are likely to raise, based on my product, site and codebase if you can see them.
- Campaign ideas and segments worth testing, with the reason for each.

Safety rules:
- Show every change as a dry run (--dry-run) first and wait for my yes. Never send emails, launch campaigns or delete anything without my yes.
- Tell me before anything that spends credits, and how many.

Be opinionated. If the docs give a sensible default, just use it. Don't make me choose between five options.
