Enter your event date and timezone. You get suggested send dates for a full email sequence. You can shift the whole sequence earlier if your sales cycle is long or compliance review is slow.
| Send date | Timing | |
|---|---|---|
| Save the date | Mar 6, 2026 | 120 days before |
| Registration open | Apr 5, 2026 | 90 days before |
| Early-bird reminder | Apr 20, 2026 | 75 days before |
| Agenda reveal | May 20, 2026 | 45 days before |
| Last chance early bird | Jun 4, 2026 | 30 days before |
| Logistics & travel | Jun 20, 2026 | 14 days before |
| Final details | Jun 27, 2026 | 7 days before |
| Day-before reminder | Jul 3, 2026 | 1 days before |
| Thank you + survey | Jul 5, 2026 | 1 day after |
Shift dates if your audience is global. One hour can change when an inbox feels quiet. Always align the final schedule with your registration platform so reminders match open and close times.
How to use this tool
Step 1: Pick your event date on the calendar.
Step 2: Choose how many weeks before the event you want the first send.
Step 3: Review the suggested schedule for each email in the list.
Step 4: Copy the dates into your ESP or project plan.
Why event planners use this
Late invites hurt registration. Early spam annoys people. A dated sequence keeps attention without burning goodwill.
Different audiences need different spacing. Corporate guests may want more notice. Local community events can run a shorter arc. Start from this schedule, then adjust after one learning cycle.
Pair these dates with the copy ideas in our AI event email guide so each send has a clear job.
When you move dates into software, tools like HubSpot can automate the sends once your content is ready.
Draft subject lines with how to use ChatGPT for event planning prompts, then check that deadlines still match your run-of-show document with AI timeline.
Subject lines and send time matter as much as the date. A good schedule with weak subjects still underperforms. Test one variant on a small segment when you can. Keep the control version for the wider send so you learn something useful.
Compliance and internal review can add a week you did not plan for. Legal, brand, and procurement sometimes need parallel tracks. Build that time into the plan before you promise a public launch date.
Example output
Scenario. A ticketed conference 10 weeks away with early-bird pricing.

Frequently asked questions
- How far in advance should a save-the-date go?
- For many business events, 8 to 12 weeks works. Large conferences with travel often need longer. Local community events can be shorter. Match the window to how far your audience must book travel. If you are late, be honest in the subject line and give one clear action.
- What if my event is free?
- You can tighten the sequence because there is no payment step. You still need reminders so people add the date to their calendar. Free events compete with other free time. Clarity beats cleverness in the subject line.
- Do I need different dates for VIPs?
- Yes. Speakers, sponsors, and board guests often need earlier holds and different tone. Send a simple private schedule for those groups. Keep the public sequence focused on attendees.
- How do I handle time zones?
- Pick one reference time zone for the plan, then list key cities if your audience is split. Schedule sends so the first open happens in business hours for your largest segment. Avoid 3 a.m. sends unless your data proves they work.
- Should weekends count?
- Count calendar days for spacing, but expect lower opens on weekends for B2B lists. Consumer audiences may behave differently. Let your past open data guide the choice.
- Can I pause the sequence?
- Yes. If you sell out early, stop hard-sell reminders and switch to logistics content. Update the calendar so your team does not send the wrong message after capacity is gone.
