Blast a list without burning your domain
Send a bulk email or SMS to a segment the safe way: consent checked, list cleaned, send throttled, and results measured before the next one.
- 1
Qualify the audience first
From a smart list, confirm: every contact opted in, DND excluded (bulk actions respect DND, but check your counts), and the segment is genuinely relevant to this message. Relevance is deliverability.
- 2
Clean before you send
Drop hard-bounced emails and landline numbers from the segment. Blasting known-bad addresses tells inbox providers you do not care.
- 3
Use drip mode for size
In the bulk action, send in batches (for example 100 every 15 minutes) instead of one dump. Spikes trigger spam filtering and carrier scrutiny; drips look human.
- 4
Send the test five
Fire the exact message to five internal addresses and numbers first. Check rendering, links, merge fields, and the unsubscribe link.

Schedule inside the window
Late morning midweek is a safe default. Never blast at night; see the quiet hours SOP.
- 6
Read the results in 48 hours
Opens and clicks are directional; complaints and bounces are law. A complaint rate above a fraction of a percent means smaller, more relevant segments next time.
Do it with Claude
Have Claude pre-flight the segment through the MCP: consent tags present, DND excluded, bounce history clean, and a draft of the message tuned to that exact audience.
Watch out for
- One giant blast to everyone, which trains providers to junk you.
- No test send, and 4,000 people receive Hi {{contact.first_name}} with the merge broken.
