Deliverability
Email verification and deliverability before the first SDR send.
Outbound deliverability is easier to protect before damage happens. For a founding SDR launch, the safest workflow is low-volume, signal-based sending with verified contacts, clear suppression rules, and careful bounce review.
01
Verification starts after list QA
The correct order is account fit, buyer match, dedupe, suppression, then email verification. This protects credits and keeps the final send list clean.
- Remove duplicates and bad-fit companies first.
- Confirm the buyer title is relevant to the offer.
- Verify only the rows that may actually be contacted.
- Keep the verification result in the lead sheet for auditability.
02
Different verification statuses need different rules
A valid email is usually safe to send when the account also fits. Invalid should be removed. Catch-all and unknown records need a stricter decision because they may increase bounce risk depending on the mailbox and domain setup.
- Send valid records first.
- Hold invalid records out of campaigns.
- Use catch-all records only when account quality is high and volume is low.
- Avoid role-based addresses for founder SDR launch campaigns unless there is a specific reason.
03
Low-volume relevance beats aggressive volume
A new outbound system should learn before it scales. Start with a small number of high-confidence contacts, watch bounces and replies, then expand. The first goal is evidence that the account logic and message angle are right.
- Use warm, human-readable copy rather than template-heavy blasts.
- Keep sequence volume conservative on new or lightly used domains.
- Track bounces, positive replies, not-now replies, and wrong-person replies.
- Improve sourcing rules before increasing send volume.
Checklist

- 01Account and buyer QA completed before verification.
- 02Suppression list checked.
- 03Valid, catch-all, unknown, invalid, and role accounts separated.
- 04Sending starts with high-confidence valid records.
- 05Bounce and reply labels are reviewed daily during the first test.
- 06Sequence copy includes a clear business reason to reach out.
FAQ
Direct answers for search and buyers.
Can I upload the same sheet directly to ZeroBounce?
Yes, if the sheet has an email column and the list has already passed account QA. Export the email column or a CSV with email plus ID, verify it, then merge the result back into the lead sheet.
Should catch-all emails be used?
Catch-all records should be treated carefully. They may be usable in very small, high-fit batches, but valid emails should be prioritized first.
Does ClickChain send spam lists?
No. The ClickChain workflow is built around low-volume, signal-based outreach, source evidence, and verification before sending.
