How many replies should a cold email get?

It varies a lot by list and offer, so there is no honest single number. What matters is the trend: if a batch of 50 gets zero replies and zero bounces, fix the list and the first line before sending more.

How long should I wait before deciding a campaign failed?

Wait until the full sequence has run, which is about two weeks for four emails. Judging after the first email misses the replies that arrive on the second and third.

Should I change the subject line first?

Only after you check the list and the ask. A short, plain subject that names something specific to them is enough. Clever subject lines rarely rescue a wrong list.

Is it worth emailing the same people again later?

Yes, after a gap of a few months, with a new reason to write. Anyone who unsubscribed or said no stays off the list.

Cold email, diagnosed

Why is nobody replying to my cold emails?

Most cold emails get no reply because they reach the wrong person, say too much, ask for too much, or stop after one try. Check the list first, then the first line and the ask, then whether you followed up at least three times. Those four fixes explain most silent campaigns.

Check these causes in this order

Work from the cheapest check to the hardest. Do not rewrite your whole pitch before you know the right people are reading it.

The order below is by how often each one is the real problem in small outbound campaigns. It is a judgment, not a measured statistic, so treat it as a sequence to check, not a promise.

Cause	How to check it	Fix
1. Wrong people	Read 20 names on your list. Would each one buy this?	Cut the list to people with a clear reason to care
2. Too long	Can you read it on a phone without scrolling?	Cut to 4 or 5 short sentences
3. Big ask	Does it ask for 30 minutes on the first email?	Ask one easy question instead
4. No follow-up	Did each person get only one email?	Send 3 follow-ups over about two weeks
5. Spam folder	Do friends with Gmail see it in the inbox?	Lower volume, shorter email, honor opt-outs
6. Weak offer	Would you reply to your own email?	Say what changes for them, with one example

1. You are writing to the wrong people

This is the usual culprit and the one people skip, because it feels like a data problem and not a writing problem. A great email to someone who does not have the problem gets no reply.

Test it. Pick 20 names at random from your list and write one sentence for each: why would this person want my offer this month? If you can answer for fewer than 15, the list is the problem. A list of 80 people who plausibly need you beats 800 maybes.

Pick a role, a type of business and a place, and say it as one sentence: office managers at dental practices in Ohio. If you cannot, narrow it. Our guide to building a lead list walks through it.

2 and 3. The email is long and the ask is big

People decide in two seconds whether to read an email from a stranger. A long email with three paragraphs about your company reads like an advertisement. Mention the person, one specific reason you wrote, and one question.

The ask matters as much as the length. "Can we get on a call for 30 minutes next week?" is a big ask from someone they have never heard of. "Do you handle gutter work in house?" takes five seconds to answer. Here is a fictional example:

Subject: Gutters at Brandt Row Hi Marcus, I run Halloran Gutter Care. We clean about 30 townhome communities on the north side. I saw Brandt Row has two downspouts hanging loose on the east building. Is gutter work something you handle in house? If yes, no worries. Dana Halloran Halloran Gutter Care, 12 Example Ave, Dayton, OH 45402 Reply "stop" and I will not write again.

The question is easy to answer either way. Both "yes, in house" and "send me a quote" are replies.

4. You only sent one email

A single email is a very common reason for silence, and the easiest to fix. Busy people miss the first message, mean to answer and forget, or read it on a phone and move on. A second and third email catches them.

A plan that works for most small senders: the first email, then three follow-ups over about two weeks, each one short and each one adding something, like a question, a small fact, or a plain "should I close this out?" We cover the schedule in how many follow-ups a cold email should get.

Follow-ups only help if you send them. Doing it by hand for 80 people means 320 emails and a spreadsheet to track who answered. That is where most people quietly stop.

5. Your emails might be landing in spam

If replies were coming and then stopped, or if you send from a brand-new inbox at high volume, spam placement is a real possibility. You cannot see a recipient's spam folder, so test it: send the same email to two or three Gmail addresses you control and look.

The causes are the usual ones. A new inbox sending too much too fast, a list with bad addresses that bounce, recipients marking you as spam, a message that looks mass-produced. The fix is lower volume, a cleaner list, plain text and honoring every opt-out. Our page on why emails go to spam has the detail.

No tool can guarantee inbox placement. Anyone who says otherwise is selling something.

6. Your offer does not say what changes

Read your email as the recipient. After you finish, do they know what would be different in their week if they said yes? "We help companies grow" is not an offer. "We cut the time to quote a roof from three days to one" is.

Use one concrete result or one concrete example, not a list of features. If you have no result yet, describe the job you do and who you do it for in plain words.

Where Rocketship does the fix

Rocketship is one product that gets you customers, and several of these fixes are steps inside it. It finds buyers by name from the kind of business and role you describe, so the list starts narrow. It sends from your own Gmail, not a shared pool, and each new inbox ramps up gradually to a ceiling of 60 cold emails a day. It follows up on its own and stops the sequence when someone replies, books or unsubscribes.

It works with Gmail and Google Workspace only. Importing your own contacts is free, including exports from Apollo and HubSpot. See plans and pricing: Launch is $24.99 a month with a 7-day free trial, card required. Answering your existing phone number is included; a dedicated line is $5 a month.
