Music promotion email deliverability

Mailbox providers score the sender before they score the message. The first signal is authentication: does the domain say this server may send for it, is the message cryptographically signed, and does the domain publish a policy for failures. Without all three, a new sending domain is treated as suspicious from the first message.

The second is reputation, which is earned per domain and per IP: how much you send, how many recipients complain, how many addresses hard bounce, and whether recipients open and reply. The third is list quality, which you control directly. The fourth is consistency: a domain that sends forty emails a week and then four thousand in an hour looks like a compromised account, because that is the most common pattern.

A Gmail or Outlook address used to send outreach is a poor sender for cold or semi-cold email. The mailbox belongs to a consumer provider with strict limits, the sending domain is not yours, and any complaint affects an account you may need for personal mail. It also tells the recipient something: an artist pitching a playlist from a free address has not invested in the infrastructure the pitch claims to deserve.

A managed domain mailbox solves the mechanics without requiring you to run a mail server. That is the specific problem a managed SMTP service addresses: a domain, a mailbox and the DNS records configured, so the first send is authenticated rather than experimental. If you run your own, the minimum is a subdomain for outreach, SPF and DKIM published, DMARC in monitoring mode, and a warm-up period before any real volume.

Hard bounces are the clearest negative signal available. Every send should be followed by removing hard bounces permanently; soft bounces can be retried once. Invalid syntax, dead domains and role addresses should be filtered before the send, not after. Verification catches most of that, and the email-list hygiene guide covers the routine.

Complaints are the other signal. They come from people who did not expect the email, which usually means the list was bought, scraped or recycled. There is no copy fix for that. If your complaint rate rises, stop the campaign, identify which segment produced it, and remove the segment rather than the sentence that mentions it.

Open rates are unreliable now: privacy features pre-fetch images and Apple’s Mail Privacy Protection inflates opens for many lists. Use replies and clicks as the real signal, and use bounce and complaint rates as the health signal. A campaign with 30 percent opens, no replies and a 4 percent complaint rate is a failed campaign whatever the open number says.

Also distinguish "not delivered" from "delivered but ignored". A message that lands in the promotions tab is delivered; a message blocked by the recipient server is not. Most outreach tools show these differently, and the difference tells you whether to change the list or the domain. For the campaign-side view of this, see music promotion that actually works.

An artist sends 400 playlist pitches from a new domain in one afternoon. Almost nothing gets a reply and the few that do say the message was in spam. The diagnosis is structural, not editorial: the domain has no DMARC record, the volume jumped from zero to 400, and the list includes addresses from an old spreadsheet with no verification date.

The fix takes six weeks. Publish SPF, DKIM and DMARC in monitoring mode; move outreach to a domain mailbox; verify the list and remove hard bounces; send 20 to 30 emails a day from the new domain, steadily, to engaged contacts; then increase to the wave size the plan allows. Copy changes come last, because the copy was never the problem.
