Email Marketing Calendar
Key send dates by season
What is it?
A reference list of recurring high-volume send dates — Black Friday, major regional shopping and cultural holidays, and similar.
Why it matters
Sending volume spikes around these dates strain deliverability infrastructure, and inbox providers tighten spam-filter scrutiny right when everyone else is also sending more.
Impact if ignored
Purely a planning reference — there is no pass/fail check here.
Common use cases
- Planning a campaign calendar in advance
- Deciding when to start warming up new sending infrastructure
