Dan Harris put a specific question to his LinkedIn network: private aviation quoting platforms are increasingly automating the follow-up email that lands after a charter quote goes unanswered. Does that nudge actually help the client move toward a decision, or does it just add to an inbox that's already full of quotes nobody asked to be reminded about?

Forty-one people voted. The result wasn't close — 63% called the emails unneeded, 37% called them a useful reminder. What made the thread worth reading wasn't the split, though. It was that none of the six comments defended blanket automation as a good idea on its own. The real disagreement wasn't over whether to automate. It was over what a follow-up email has to contain before a recipient is glad they opened it.

What the Data on Follow-Up Emails Actually Shows

Follow-up emails, as a category, are not the problem — the research on this is fairly consistent. Belkins' 2026 study of more than 7.5 million B2B outreach emails found that follow-up messages collectively account for 58.6% of all replies in a sequence, even though the very first email in a sequence has the highest per-message reply rate on its own. Separately, Cirrus Insight's analysis of tens of millions of emails found that sending at least one follow-up lifts the average reply rate from roughly 9% to 13%. The catch is that these numbers describe well-built, targeted sequences — not blanket automated reminders sent to everyone who hasn't responded yet. Reply rates industry-wide have also been sliding for years: one 2026 benchmark from Instantly put the average cold-outreach reply rate at 3.43%, down from roughly 8.5% in 2019, as inboxes get more crowded and more of what lands in them is templated.

There's no public dataset on how charter clients specifically respond to automated quote follow-ups — this is a narrow enough use case that nobody has published it yet. The closest data-rich comparison is e-commerce cart-abandonment email, which runs on the same underlying logic: a prospect showed real interest, then went quiet. There, well-timed automated reminders convert roughly 5% to 10% of recipients on average, according to Klaviyo's benchmark data, with the best-performing flows reaching into the mid-teens. The gap between average and top performers comes down to relevance and timing, not whether the message was automated in the first place.

Why the Automation Is Showing Up Now

What Dan noticed on LinkedIn is a real industry trend, not an isolated anecdote. The major charter quoting platforms have built follow-up and communication automation directly into their sales workflow over the past few years. FL3XX's AI: Quote feature turns an inbound email into a structured quote automatically, with all client communication threaded to the trip record inside the platform. Leon Software's Sales module includes automated messaging and quote-handling tools built around its Avinode marketplace integration, so a broker's back-and-forth with an operator happens inside the same system that tracks the quote itself. Neither platform publishes data on how clients respond to the automated follow-ups their own software generates — which is exactly why an informal, 41-vote poll of people who actually receive these emails is a more useful data point than it might first appear.

What Separates a Reminder From Noise

In the comments, the sharpest response came from someone who handles charter desk communication directly: automated follow-ups earn their place only when they add something the client doesn't already have, rather than repeating what the original quote already said. The example offered was almost aggressively simple — a single line asking, "Would you like us to keep this option open for you?" One clear ask, no recycled information, no filler.

A charter brokerage founder in the same thread made a related but separate point: the format isn't really the issue. A follow-up can be system-generated and still read like someone paying attention, or it can be typed by a human and still land as generic. What determines whether it gets opened is whether the message carries real investment in that specific trip — not whether a person or a script sent it.

The Practical Takeaway

For operators and brokers building these sequences, the poll result is less an indictment of automation and more a diagnosis: most automated follow-ups fail the same three tests. They repeat information the client already has instead of adding something new. They run on a fixed schedule instead of the client's actual decision window. And they read like a system, not like someone who remembers the specific trip. Fix those three things and the follow-up starts to look a lot more like the reply-boosting sequences in the B2B data above, and a lot less like the 63% of respondents who called it noise.

For clients on the receiving end, the practical filter is simpler than it seems: an automated follow-up worth opening tells you something new or asks you something specific. One that just resends the quote you already have is safe to archive.
