In short
- Pre-send checks should catch risk before recipients do.
- Sending must be controllable and stoppable mid-flight.
- Post-campaign review needs per-recipient reasons.
- Reusing a past campaign should take seconds.
Stage 1 — Drafting
You need a subject line, an HTML body, personalization fields mapped to your list columns, and a preview. AI assistance helps here: BulkMailer uses NVIDIA AI to draft the subject and body from a short brief about your offer and audience.
Stage 2 — Pre-send checks
- Merge-field validation against the actual list columns.
- HTML safety and structure review.
- Spam-risk wording review on subject and body.
- SPF, DKIM, DMARC, and MX confirmation for the sending domain.
- A real test send to your own mailbox.
Stage 3 — Controlled sending
Set the rate and concurrency, then watch it run. BulkMailer sends one recipient at a time in real time, records the SMTP response for each, retries transient failures, and fails over to another SMTP server when one degrades. You can pause or stop at any point.
Stage 4 — Review and reuse
After the send, read the failure reasons before the totals. Repeated hard bounces mean list quality; repeated blocks from one provider mean reputation or authentication. Then duplicate the campaign for the next round rather than rebuilding it.
Checklist
- Map every merge field used in the body.
- Run the spam and HTML checks.
- Send a test to yourself and read it on a phone.
- Set a conservative send rate.
- Review failure reasons before reporting results.

Questions people ask
Can I stop a campaign that is already sending?
In BulkMailer, yes — sending is recipient by recipient, so a campaign can be paused or stopped mid-flight instead of running to completion.
Can I send several campaigns at once?
Yes. Concurrent sends are supported with per-campaign rate limits so they do not overwhelm a single SMTP server.
What happens when one SMTP server fails?
Transient failures are retried, and sending can fail over to another healthy SMTP server configured in your account.
