Silence Isn’t a No: How Many Follow Up Emails MSPs Should Send

By Jim Punzenberger, founder of Managed Prospecting System and former MSP owner

More than half of cold email replies arrive after the first message, which changes how many follow up emails MSPs should send. In a Belkins study of 7.5 million emails sent during 2025, follow-ups produced 58.6% of all replies, and the third email booked more meetings than the first two combined.

Why a Quiet Inbox Is Not a Rejection

A prospect who skips your first email has not told you anything yet. They might have read it on a phone between client calls. They might have meant to answer on Friday and lost it under forty newer messages. Silence can mean a busy week just as easily as it means no.

The trouble starts when an IT company reads that silence as a decision. The campaign gets switched off after one or two sends, and the list gets written off as cold. The prospects who would have replied to the third email do not get the chance to see it.

There is one exception worth ruling out first. If your emails are not reaching the inbox at all, more follow-ups will not help, and the fix starts with why MSP cold emails land in spam folders. Once delivery is sound, the question becomes how long you stay in front of the buyer.

Signs Your Sequence Stops Too Early

  • The whole campaign is one email followed by a long wait.
  • Your second email says “just bumping this up” and nothing more.
  • Each follow-up repeats the first message in slightly different words.
  • You judge the list dead before the third send goes out.
  • You have no record of which step produced each reply.

What the Numbers Say About Each Step

Belkins tracked replies and booked meetings step by step across a full year of outreach. The first email had the highest reply rate of any single step, at 0.59%. That looks like an argument for stopping early, until you add the later steps together.

Steps two through six produced 58.6% of all replies, while the first email captured 41.4%. Meetings tell an even sharper story. Step three alone drove 35.6% of email-sourced meetings, more than steps one and two combined, and steps three through five drove 53.5%.

Here is how each step in a typical sequence lines up against that data.

Step Its job in the sequence What the Belkins data showed
Email 1 Open with one specific, relevant problem Highest single-step reply rate, at 0.59%
Email 2 Add one new piece of proof Part of the 58.6% of replies from follow-ups
Email 3 Reframe the problem with sharper relevance Drove 35.6% of all email-sourced meetings
Email 4 Try a genuinely different angle or hook Reply rate ticked up to 0.34% from 0.30%
Email 5 Close the thread politely and clearly Returns diminish quickly beyond this step
Email 6 Move the contact to LinkedIn instead Reply rate fell to 0.28% at this step

Why the Third Email Carries So Much Weight

Belkins offers a likely explanation for the step three effect. The prospects still in a sequence by then have not unsubscribed, opted out or said no, so they form a more engaged group. According to the study, a meaningful share of decision-makers need two earlier touches before they engage with a meeting request.

Think about how that plays out for a dental practice owner with twelve staff. The first email registers as a name. The second one gets read but parked. By the third, your name is familiar, and a sharper message about their specific problem has a real chance of landing on a quieter afternoon.

So, How Many Follow Up Emails MSPs Should Send

The practical answer is three to five emails in total, which means two to four follow-ups after the first send. Belkins describes three to five steps as the sweet spot for most B2B email sequences, with value falling off fast after step five. That range gives a busy owner several chances to notice you without turning your name into noise.

Spacing them several business days apart keeps the thread alive without feeling like a chase. The count matters less than what changes between sends. A sequence of four identical emails is really one email sent four times.

Patience applies at the campaign level too. A new sequence can look flat for weeks before replies build, which is why how long MSP lead generation takes to work is worth understanding before you judge the results.

Give Each Follow-Up a New Reason to Reply

A bump asks the prospect to do your work for you. A good follow-up brings something the first email did not, so the reader has a fresh reason to answer. Belkins makes the same point about step four, where a different hook can outperform a third email that reads like a copy of the first.

These angles work well as the second, third and fourth messages in a sequence:

  • A second problem the same type of buyer is likely facing.
  • A short proof point from a similar business nearby.
  • A direct question that takes ten seconds to answer.
  • A relevant change in their industry, insurance or compliance rules.
  • A clear close that makes saying no easy and respectful.

Keep each message short and send it in the same thread, so the earlier context sits right below it. This work gets far simpler when the list is narrow. Once you know how to choose a niche for your MSP, the second and third problems are much easier to name with confidence.

When Email Goes Quiet, Change the Channel

A finished email sequence does not have to mean a finished conversation. Belkins measured LinkedIn reply rates above 7% across all twelve months of 2025, with no seasonal dip. A connection request that mentions your earlier email bridges the two channels and gives the prospect context.

Calling also played a large role in the same dataset, driving 33.6% of all appointments booked. The study frames the call as an escalation step, most useful after email and LinkedIn have already built some recognition. Deciding how many follow up emails MSPs should send is really a decision about how long you stay visible, and email is only one way to do it.

A simple cross-channel follow-up path for a small IT company looks like this:

  • Send three to five emails, each one with a new angle.
  • Connect on LinkedIn with a note that references the email.
  • Send a short, conversational message once the connection is accepted.
  • Pick up the phone after both channels have built recognition.
  • Log which touch produced each reply, so you can repeat it.

Know When to Stop, and When to Come Back

Past step five, Belkins saw returns diminish quickly, and step six added very little. Pushing beyond that point spends goodwill you may want later. Respect every opt-out immediately and remove that contact from future sends.

Stopping a sequence is not the same as giving up on a prospect. Belkins names the first quarter as the highest-leverage window for email follow-up across the year. A prospect who stayed quiet in November can receive a fresh sequence in January, built around a new reason to talk.

That makes the next few weeks valuable setup time. Our guide to how MSPs build pipeline during the holiday slowdown covers how to get that January list and those emails ready now.

Frequently Asked Questions

How many follow-ups should I send before I stop?

The working answer to how many follow up emails MSPs should send is two to four, for three to five emails in total. That matches the range Belkins found most productive, and returns diminish quickly after step five.

Is it pushy to send a third or fourth email?

It is not pushy when each message adds something new and the tone stays respectful. Belkins found the third email booked more meetings than the first two combined. A meaningful share of decision-makers need a couple of touches before they engage.

What should I do when a sequence ends with no reply?

Move the conversation to LinkedIn, where Belkins measured reply rates above 7% throughout 2025. If that stays quiet as well, rest the contact and return next quarter with a fresh angle.

Good Copy, Zero Replies: Why MSP Cold Emails Land in Spam Folders

By Jim Punzenberger, founder of Managed Prospecting System and former MSP owner

When a sharp campaign gets zero replies, find out where the emails landed before you rewrite a single line. Why MSP cold emails land in spam folders comes down to four fixable causes: an unproven sending domain, spam complaints, dead addresses on the list, and a sending pattern that looks like a bulk blast.

The Delivered Number Is Not the Inbox

Your sending tool says 98 percent delivered, so the emails must have arrived. That number means something narrower. Validity, which tracks inbox placement across hundreds of mailbox providers, notes that most sending platforms calculate delivery as sent minus bounced. It tells you the receiving server accepted the email, not where the email went next.

Where it went next decides whether anyone replies. Validity’s 2025 Email Deliverability Benchmark found that one in six legitimate marketing emails failed to reach the inbox.

  • 83.5 percent of emails reached the inbox globally.
  • 6.7 percent landed in spam, and 9.8 percent went missing, blocked or deferred before reaching either folder.
  • Spam placement nearly doubled across 2024, from 4.5 percent in the first quarter to 8.6 percent in the fourth.

Those figures come from permission-based marketing, email that recipients signed up to receive. Validity also notes that B2B senders with a low bar for consent end up with less engaged lists and weaker sender reputations. A cold list starts with no consent at all, so there is little reason to expect it to beat those averages.

Placement also varies widely by provider, and business inboxes were no easier than personal ones.

Mailbox provider Inbox Spam Missing
Gmail 87.2% 6.8% 6.0%
Yahoo/AOL 86.0% 4.8% 9.2%
Office 365 (business) 85.2% 3.1% 11.7%
Google business accounts 83.1% 5.9% 11.1%
Apple 76.3% 14.3% 9.4%
Microsoft (Outlook, Hotmail) 75.6% 14.6% 9.8%

The business inbox figure deserves the closest look. Among the business email platforms Validity measured, Office 365 carried 61.4 percent of the traffic. When you email a dental office or a law firm, the filter deciding your fate is likely Microsoft’s.

Why MSP Cold Emails Land in Spam Folders

Mailbox providers decide placement from signals about who you are and how recipients react to you. Four of those signals matter most for cold outreach, and all four are fixable.

Your Domain Cannot Prove Who It Is

Google requires all senders to authenticate with SPF or DKIM, and anyone sending 5,000 or more messages a day to Gmail must have SPF, DKIM, and DMARC in place. In plain terms, SPF lists the servers allowed to send for your domain. DKIM adds a signature proving the message was not altered. DMARC tells the receiving server what to do when those checks fail.

Skip them and you are asking a filter to trust a stranger. Google’s own FAQ warns that when authentication fails, mail from a domain with no DMARC policy might be rejected or sent to spam.

You set these records up for clients, and a prospect who checks your headers will expect you to have them right. Validity found that over 90 percent of new DMARC adopters in early 2024 chose a “none” policy, which monitors but does not enforce. A record that exists is not the same as one that protects you.

Recipients Are Hitting the Spam Button

Google asks senders to keep the spam rate shown in Postmaster Tools below 0.3 percent. That works out to three complaints per thousand emails, and Validity calls the threshold generous. Its advice is to stay below 0.1 percent, yet only a quarter of senders polled at one of its webinars were there.

Validity describes complaint rates as the single biggest factor pulling down sender reputation. In cold email, complaints come from messages that feel generic, irrelevant, or hard to escape. A prospect who cannot find a way out is more likely to reach for the spam button.

The List Is Full of Dead Addresses

People change jobs, companies change domains, and mailbox providers delete inactive accounts. Validity reports that Gmail and Yahoo both delete dormant accounts, and that sending to those deleted addresses raises unknown-user rates and hurts sender reputation.

A list pulled from an old database carries that decay straight into your first send. Bounces tell the receiving server the list is not being managed. If you build lists yourself, the groundwork in how to build a winning prospect list matters as much as the copy.

The Sending Pattern Looks Like a Blast

Three hundred identical emails at 9:00 a.m. from a domain registered last week looks like a machine, because it is one. Validity reports that mailbox providers see a surge of traffic in the first minute of each hour from scheduled sends. During those spikes, more mail gets throttled, filtered to spam, or blocked.

Sending cold outreach from your main company domain adds a second risk. If the campaign damages that domain’s reputation, the fallout can reach the invoices, tickets, and client emails that run your business.

Warning Signs Your Campaign Is in the Spam Folder

Mailbox providers do not send a notice when they filter you. The signs show up in your numbers instead.

  • Replies stop suddenly while the copy, list, and offer stay the same.
  • Replies come from Gmail addresses but not from Outlook or Office 365. Microsoft had the lowest inbox placement of the major providers in Validity’s report, at 75.6 percent.
  • Bounce notices climb from one send to the next.
  • A test email to your own Gmail and Outlook accounts lands in junk.

How Do You Keep Cold Email in the Inbox?

Knowing why MSP cold emails land in spam folders is half the job. The other half is a setup that keeps them out, and none of it involves rewriting your copy.

  • Send from a separate domain. Register one close to your brand so a rough campaign stays away from the email your clients rely on.
  • Authenticate it fully. Publish SPF, DKIM, and DMARC, then move DMARC from “none” to “quarantine” once reports come back clean, as Validity recommends.
  • Warm new mailboxes before campaigns. Start with low daily volume and raise it gradually so the domain earns a sending history.
  • Verify addresses before they load. Remove bounces after each send instead of letting them pile up.
  • Offset send times. Schedule away from the top of the hour.
  • Treat complaints as opt-outs. Suppress anyone who marks you as spam or asks to stop, which Validity lists as a core deliverability habit.

Then watch the data. Google Postmaster Tools shows the spam rate Gmail records for your domain. A weekly test send to Gmail and Outlook accounts shows placement before a whole campaign disappears.

Where Good Copy Still Earns Its Keep

Deliverability gets you seen. Copy still decides whether anyone replies, and the two feed each other. A relevant, specific first email draws fewer complaints, fewer complaints protect your reputation, and a stronger reputation puts the next email in front of the prospect.

Relevance in cold outreach is narrow. It means writing to one kind of business about one problem that business recognizes, with a single easy question at the end. The broader the message, the more recipients read it as noise, and noise is what the spam button is for.

That loop is also why a campaign needs a checkable number. Contacts, placements, replies, and meetings each tell you which stage broke, the same argument behind measuring what MSP lead generation costs per booked meeting. A campaign judged only by “no replies yet” cannot tell a copy problem from a spam folder. To see how we connect those pieces, read how Managed Prospecting System works.

Frequently Asked Questions

How do I know if my cold emails are going to spam?

The quickest diagnosis of why MSP cold emails land in spam folders is a test send to Gmail and Outlook accounts you control. Compare reply rates by provider too, since silence from one provider alone points to filtering. If you send enough volume to Gmail, Postmaster Tools reports your domain’s spam rate directly.

Do SPF, DKIM, and DMARC guarantee inbox placement?

No. They prove your mail comes from you, which gets it considered rather than rejected. Complaints, list quality, and sending behavior still decide placement, and Validity notes that business email administrators can set custom filtering rules that are usually stricter than the defaults.

Should an MSP send cold email from its main domain?

A separate sending domain is the safer choice. It builds its own reputation for outreach while your main domain keeps handling client email, invoices, and support. Point the sending domain’s website to your main site so prospects who check it still find you.
