When users attempt to send an email campaign to a large audience (ex: 250+ contacts), there should be a built-in safeguard that prompts them before sending.

Proposed behavior:

If a campaign exceeds a defined threshold (ex: 250 recipients), trigger a pre-send warning

Display a message explaining the risk of sending all at once vs using scheduled/drip delivery

Example warning message:

“You're about to send this campaign to a large number of contacts at once. Sending in bulk may increase the risk of deliverability issues or domain reputation damage.

We recommend using drip scheduling to space out sends.”

Options in the prompt:

Continue sending immediately

Switch to drip/scheduled sending

Cancel

Additional option:

Checkbox: “Don’t show this again”

Why this matters

Protects users from hurting domain reputation

Reduces spam flagging and blacklisting risks

Helps newer users follow best practices without needing to learn the hard way

Aligns with how experienced email marketers already operate
