Your Open Rate Is Mostly Fiction.

As a scoreboard, no. As a smoke alarm, yes. Apple Mail Privacy Protection pre-loads tracking pixels for Apple Mail users, which means roughly half of all reported opens are machines rather than people. Reported averages sit at 42 to 44%, inflated by an estimated 15 to 20 percentage points. What open rate is still good for is spotting a sudden drop, which usually means a deliverability problem. Lead with click rate instead, which nothing has corrupted, then click-to-open rate, then revenue per email sent.

Campaign click rates have hovered between 2.0% and 2.5% for three consecutive years across most published benchmarks. Automated flows run far higher, commonly around 5.6%, because they fire when someone has just done something rather than on a calendar. Click-to-open rate currently averages near 6.8%, up from about 5.6% two years ago. The averages hide a widening gap: senders who segment and automate are pulling away from senders who send the same thing to everyone.

Usually authentication or complaints rather than content. Since February 2024 the major providers require SPF, DKIM, DMARC, a one-click unsubscribe header and a spam complaint rate under 0.3% from bulk senders. Roughly 30% of senders are still non-compliant on at least one of those, and non-compliant senders see spam-folder delivery jump from a 5 to 10% baseline to between 22 and 34%. Authenticated domains are reported to be around 2.7 times more likely to reach the inbox. Run through the compliance checklist on this page first.

For bulk senders, meaning roughly 5,000 or more messages a day to personal accounts at those providers: SPF and DKIM authentication, a published DMARC policy, a one-click unsubscribe header that mail clients can act on directly, and a user-reported spam rate kept under 0.3% with under 0.1% recommended. These took effect in February 2024. Google moved from temporary deferrals to permanent rejections in November 2025 and Microsoft began enforcing in May 2025. Microsoft has signaled similar requirements for its consumer mail rolling out in phases.

Flows, and it is not close. Ecommerce data indicates automated flows produce around 41% of email revenue from about 5.3% of sends. Campaigns get almost all the attention because they feel like work, while the welcome sequence sits untouched for two years. Welcome emails have been reported at open rates above 80% and click rates near 17%, several times what a broadcast achieves. Build welcome, cart or form abandonment, and post-purchase first. They run for years without further effort.

Often enough that people remember who you are, rarely enough that they do not resent it, and consistently enough that your sending pattern looks stable to mailbox providers. For most businesses that is somewhere between weekly and monthly for campaigns, with flows firing whenever they are triggered. The honest answer is that frequency matters less than relevance. A segmented list can take more mail than an unsegmented one, and complaint rate is the number that tells you when you have crossed the line.

No, and the reason is more serious than most people realize. Purchased lists produce bounces and complaints, and complaint damage does not reset when the campaign ends. It compounds against your sender reputation across your entire domain and affects every email you send afterwards, including transactional mail. One careless send can degrade a program for months. If you want to reach people who have not opted in, cold email exists, but a competent email marketing company runs it on separate domains with separate reputations precisely so it can never touch your main sending.

Most email marketing companies charge a monthly retainer, and it varies widely depending on whether flows are being built from scratch, how many campaigns are produced, and whether deliverability work is needed. We price to the work rather than publishing tiers. What is worth knowing is that the highest-value work is front-loaded: deliverability fixes and flow architecture take effort once and then keep earning, so the first quarter is typically heavier than what follows.
