MSP newsletter open rate benchmarks (2026)

A 30% open rate can mean two different things at an MSP. If you are sending to a mix of active clients and cold acquisition prospects, 30% may reflect solid client engagement dragged down by unresponsive outreach contacts you have not pruned. If you are sending to a clean client list and hitting 30%, you are underperforming the 35-44% range that named sources report for technology and IT services senders. The number is nearly meaningless without a reference point.

This page is part of our Newsletter Performance playbook — the broader guide on open rates, click-through, and ROI benchmarks.

The benchmarks below come from published research with named sources. Where multiple ESPs report the same metric differently, the range is shown rather than a single averaged figure. No MSP-only benchmark has been published by a major ESP as of 2026; the triangulation methodology is explained in the section below.

What we mean by “good” for an MSP newsletter

Short answer: For a client-only MSP newsletter, 35–42% open rate is the realistic target range. Top-quartile programs on clean lists with consistent monthly cadence and threat-advisory framing reach 42–50%. CTOR of 14–17% is the corresponding engagement target, and it is the more meaningful metric now that Apple MPP has compromised open rate as a cross-list signal.

No ESP breaks out “managed service providers” as a standalone benchmark category. The closest published figures come from three sources that cover the adjacent space:

• GetResponse 2024 — Technology & High Tech: 44.72% open rate, 7.40% CTR, 16.54% CTOR, 0.15% unsubscribe, 2.23% bounce. This is the broadest tech category and likely includes SaaS vendors and large enterprise IT, which tend to have more mature email programs.
• IT Services B2B composite (emails-wipes 2026): 35.1% open rate, 2.9% CTR, 0.13% unsubscribe. This composite sits closer to the MSP operating profile — B2B, service-led, relationship-managed contact lists rather than transactional or e-commerce audiences.
• Mailchimp — Technology/Software: 28.12% open rate, 2.39% CTR. Mailchimp's figures are older and reflect pre-MPP inflation normalization; treat them as a floor rather than a target.

MailerLite's Computers & Electronics category reports 45.65% open rate — the highest tech-adjacent figure in their 2024 data — but the category scope is wide enough to include consumer electronics retailers, which skews the figure upward. Klaviyo's B2B Services benchmark (39.48% open / 2.21% CTR / 5.63% CTOR) is the most conservative cross-ESP reference and the safest floor for planning.

The practical target range for an MSP newsletter with a clean client list: 35–42% reported open rate, 14–17% CTOR, 2.5–4% CTR, unsubscribe under 0.20%. For a list that mixes clients and prospects, add a 6–8 point discount to the open rate expectation until the segments are separated.

Note on ESP variance. The 16-point gap between Mailchimp (28.12%) and GetResponse (44.72%) for technology senders is not primarily a quality difference between ESP user bases — it reflects methodology differences, list composition, and the timing of MPP normalization in each report. Use the range rather than any single figure as your reference.

Open rate benchmarks for MSP newsletters

The table above gives the raw benchmark figures. The section below explains what they mean for an MSP program and how Apple Mail Privacy Protection changes the interpretation.

Apple Mail Privacy Protection: why your open rate is not what it appears

Short answer: Apple MPP pre-fetches the tracking pixel for every Apple Mail recipient, recording an open whether or not the message was read. Litmus 2025 data places Apple Mail at roughly 55% of all opens for B2B senders. A reported 38% open rate on an MSP newsletter likely represents about 17% true human-read. CTOR and reply rate are the post-MPP engagement signals that have not been compromised.

Since September 2021, Apple Mail Privacy Protection pre-fetches emails in the background before the subscriber actually opens them, registering an open event regardless of whether the message was read. Litmus's 2025 email client market share report places Apple Mail at approximately 55% of total opens across B2B senders — meaning more than half of every open count is potentially machine-generated.

For an MSP newsletter, where the typical client base skews toward business owners and executives who are likely Apple Mail users, the MPP distortion may run higher than average. A reported 38% open rate on a 200-person MSP client list likely reflects genuine human reads in the 17–20% range. The open rate has not become worthless: it still tells you whether subject line changes move the number in a consistent direction. But it is no longer a reliable absolute measure of content engagement, and it cannot be used to compare two lists of different Apple Mail composition.

CTOR is the correction. A subscriber who opened (whether human or machine) and then clicked — that click is real. GetResponse 2024 benchmarks Technology & High Tech CTOR at 16.54%, well above the B2B average of 8.62% (Klaviyo). An MSP newsletter with CTOR below 10% against a high open rate has a content engagement problem that the open rate is masking.

Top quartile, median, bottom quartile — what each looks like for an MSP

Short answer: Top-quartile MSP newsletters (42%+) run on established client lists with consistent monthly cadence and security-advisory framing. Median (28–37%) reflects mixed prospect/client lists with generic content. Bottom quartile (under 25%) is almost always cold prospect lists, vendor-pitch construction, or both.

Top quartile: 42%+ open rate

Top-quartile MSP newsletters share four characteristics: the list is primarily or exclusively active clients; the cadence is monthly and has not drifted in over six months; the subject line framing draws on threat advisories, peer-incident reporting, or compliance deadlines rather than product announcements; and the content is segmented by client industry at minimum (regulated vs. non-regulated, or by vertical if the MSP serves a narrow niche). GetResponse's 44.72% Technology & High Tech figure represents the ceiling for this tier; the floor is around 42%.

Median: 28–37% open rate

Median-tier MSP newsletters typically have a list that mixes active clients with prospects who opted in through a lead magnet or were added during an outreach campaign. Content is competent but generic — standard security tips, vendor updates, quarterly business reviews summarized. Cadence is roughly monthly but has slipped to six-week intervals at least once in the last year. The 35.1% IT Services B2B composite sits squarely in this range.

Bottom quartile: under 25% open rate

Bottom-quartile performance at an MSP is almost always a list composition problem, not a content problem. Cold prospects added from a purchased list, contacts from trade shows who never requested email, or a list that has not been cleaned in two or more years will all produce sub-25% open rates regardless of content quality. Mailchimp's 28.12% Technology/Software figure, which reflects pre-normalization MPP data, sits above this tier — meaning even the most conservative published benchmark clears 25%. If you are below that, start with list hygiene before optimizing anything else.

What moves an MSP newsletter from 28% to 38%

Six levers, in rough priority order. The first two are list operations; the rest are content and infrastructure decisions.

1. Segment by client industry. Regulated clients (healthcare, finance, legal) have materially different threat landscapes than trade or professional services clients. A subject line about HIPAA audit risk reads differently to a dental practice owner than to a construction contractor. Even a simple two-segment split — regulated vs. non-regulated — produces measurable open rate improvement without a complex ESP setup.
2. Replace vendor-pitch subject lines with peer-flagging diagnostics. “Q2 managed security update from [MSP Name]” is a vendor pitch. “3 firms in your industry hit by this ransomware variant last month” is a peer-flagging diagnostic — it signals that the sender knows something the reader does not, and the reader's business may be at risk. The MSP subject lines page covers the specific patterns that map to this framing.
3. Hold a fixed monthly cadence without exception. Monthly is the right default for most MSP newsletters — it is frequent enough to maintain sender recognition and infrequent enough that content quality stays high. The most common cadence failure is going silent during a busy quarter, which resets subscriber habituation. Batch content in advance if necessary. The MSP content ideas page has a 12-month topic rotation that supports advance batching.
4. Suppress non-engagers after six months. Contacts who have not opened or clicked in six months are dragging your open rate denominator and damaging your sender reputation with ISPs. Run a re-engagement sequence first — two emails with a direct ask to confirm they want to stay on the list. Suppress anyone who does not respond. The list will be smaller; every metric will improve.
5. Move to a single-sender domain with DMARC at p=quarantine minimum. Deliverability determines whether your newsletter reaches the inbox at all. A domain without DMARC authentication at quarantine or reject policy is treated with increasing suspicion by Gmail and Microsoft 365 as of 2024 bulk-sender requirements. If you are sending from a shared subdomain or have not configured DKIM and DMARC on your sending domain, inbox placement issues may be suppressing your open rate before content quality is ever a factor.
6. Cut prospect list from client list — run two separate programs. One newsletter optimized for client retention (relationship content, security advisories, account updates) and a separate drip sequence for acquisition prospects (educational content, case studies, social proof) will both perform better than a blended list trying to serve both audiences. The open rate improvement on the client-only list will be immediate and substantial.
