Can sender reputation improve beyond baseline?

Yes, reputation can improve substantially beyond where you started. Sustained excellent practices earn increasingly favorable treatment:

Premium reputation status at providers who recognize consistently clean senders. Gmail's "High" reputation and similar tiers at other providers.

Reduced filtering scrutiny where your content and links receive less aggressive spam scoring because your track record earns trust.

Faster delivery as providers prioritize mail from trusted senders over unknown ones.

Greater resilience when occasional issues occur. Established high reputation provides buffer against single bad campaigns.

Reaching premium status requires months or years of consistent, clean sending. Maintaining it requires continued discipline.

Premium reputation is like captain's club membership at every harbor. You earned it through documented excellence, and it grants privileges that make future voyages smoother and faster.
