In the US, yes, as long as you follow CAN-SPAM. That means an honest subject line and sender, your physical postal address and a working opt-out you honour within 10 business days. The law makes no exception for business-to-business email. The UK and EU are stricter, especially for emails to individuals, so check local rules before building a list there.

How many follow-ups should a cold email have?

Three follow-ups after the first email is a sensible default, so four touches in total. Instantly's 2026 benchmark puts the useful range at four to seven touches and found 42 percent of replies come from follow-ups. Space them out, for example days three, seven and fourteen, and make each one add something new instead of simply bumping the thread.

How long should a cold email be?

Under 80 words for the body is a good target. Instantly's 2026 benchmark found its top-performing senders averaged fewer than 80 words in first-touch emails. Short emails are easier to read on a phone and easier to answer in one line. If yours runs longer, cut the part about you before you cut the part about them.

What is a good reply rate for cold email?

Instantly's 2026 benchmark puts the average at 3.43 percent, with the top quarter of senders above 5.5 percent and the top 10 percent above 10.7 percent. Benchmarks vary with method and audience, so treat them as rough guides. If you sit well below average, fix the list and the opener before touching subject lines or send times.

Should I use AI to write cold emails?

Use AI for research and first drafts, not for the final send decision. AI can summarise a prospect's site and draft the four parts quickly. The risk is sameness: generic AI outreach looks like everyone else's and gets ignored or filtered. Feed it something specific about each recipient, then read every first email yourself before it goes out.

When is the best time to send a cold email?

There is no send time that rescues a weak email. Weekday mornings in the recipient's time zone are the usual default, because that is when people clear their inbox, but published studies disagree on the best day and hour. Pick a reasonable window, keep it consistent, and spend the effort on who you email and what the first line says.

Cold Email Templates: 5 That Get Replies, Annotated (2026)

A cold email template that gets replies has four parts: a subject line of three to six words that names something specific, a first line about the recipient, one sentence of relevance with proof, and a single easy ask. Keep the whole email under 80 words. The five templates below cover the situations founders actually send.

Each one is annotated: what to fill in, why the structure works, and what people usually get wrong. Copy them, but replace every bracket with something you could only know by looking at the recipient's business.

The four-part structure

Every template on this page follows the same skeleton. Learn the skeleton once and you can write any cold email without a template at all.

Subject line. Three to six words, lowercase is fine, and specific to them. "your onboarding emails" beats "quick question" because it proves you looked.

Opener. One sentence about the recipient, not about you. A real observation about their product, their hiring, their pricing page or something they published.

Relevance. One or two sentences that connect the observation to what you do, with one piece of proof: a similar customer, a number, a sample. This is the only place you talk about yourself.

Ask. One question that can be answered in a line. "Worth a 15-minute look?" is easy. "Let me know your availability for a call next week" is homework.

Length matters more than most founders expect. In Instantly's 2026 cold email benchmark, the top-performing senders averaged fewer than 80 words in their first-touch email, against a platform-wide average reply rate of 3.43 percent.

Four parts, under 80 words, and only one of them is about you

Five cold email templates you can copy

Brackets are mandatory edits, not optional flourishes. If you cannot fill a bracket for a given prospect, that prospect is not ready to be emailed yet.

1. First-touch prospect email

Use this when you sell a product or service to a business and have a specific reason to think they need it.

Subject: your [specific thing you noticed]

Hi [first name],

[One sentence about something you saw: e.g. "Your trial welcome
sequence stops after day two, right before most trials decide."]

I help [type of company] fix exactly that. [Similar customer]
[got specific result] in [timeframe] after [what changed].

Worth a 15-minute look at yours? If not, no reply needed.

[Your name]
[Company, one line]

Why it works. The opener proves research, the proof is borrowed from someone like them, and "no reply needed" makes answering feel cheap, because a one-line "not now" is clearly acceptable.

What goes wrong. Founders swap the observation for a compliment ("Love what you're building"). A compliment is not evidence of research, and readers can tell.

2. Follow-up after no reply

Most replies come from the first email, but not all of them. Instantly's benchmark found 58 percent of replies arrive on step one and 42 percent on follow-ups, with four to seven touches as the useful range. Send the follow-ups in the same thread so the context travels with them.

Follow-up one, day three. Add something new rather than "bumping".

Hi [first name],

One thing I left out: [one specific, useful idea for them,
e.g. "the two emails I would add to your trial sequence first"].

Happy to send the full version if it's useful.

[Your name]

Follow-up two, day seven. Change the angle to proof.

Hi [first name],

[Similar company] had the same [problem] last quarter.
Here's the one-page summary of what they changed: [link]

If [problem] isn't a priority right now, tell me and I'll stop here.

[Your name]

Follow-up three, day fourteen. Give them an exit. This is the one message where a new subject line earns its place.

Subject: wrong person?

Hi [first name],

I've written a couple of times about [problem]. If someone else
owns [area], could you point me to them? If the timing is off,
I'll close this out.

[Your name]

Why it works. Each message carries new information or a new way to answer. "Just following up" carries neither, so it trains the reader to ignore you.

Email one does most of the work, but skipping follow-ups leaves four in ten replies unsent

3. Supplier or manufacturer outreach

This is the cold email most templates ignore, and the one product founders send most. Factories and wholesalers get inquiries all day, so they reply first to the buyers who look quotable.

Subject: [product type] quote, [quantity] units

Hi [name],

I run [brand], a [one-line description] selling through [channel].
I'm looking for a manufacturer for [product: material, size,
finish, packaging]. Spec sheet attached.

First order would be [quantity] units, rising to [quantity] per
quarter if samples pass. Target landed cost is [range] per unit.

Could you share your MOQ, sample cost and lead time for this spec?

Thanks,
[Your name]
[Brand, website, country]

Why it works. Quantities, a spec and a target price tell the supplier you are a real order, not a student project. A specific three-part question gets a specific answer instead of a generic catalogue.

What goes wrong. Hiding your volume to seem bigger. Suppliers quote small buyers fine if they know what to expect; they ignore vague ones. For vetting the replies, see how to find and vet a private label manufacturer and the four-stage supplier sourcing process.

4. Partnership or collaboration pitch

Use this for newsletter swaps, integrations, co-marketing or affiliate deals. The rule: do the first piece of work before you ask.

Subject: [their audience] x [your audience]

Hi [name],

Your [newsletter / product / podcast] reaches [their audience].
Mine reaches [overlapping audience], about [size].

Idea: [specific swap, e.g. "I write one guest issue on X for your
readers, you write one for mine"]. I've drafted my outline here:
[link]

Open to it? If the fit's off, say so and I'll leave it there.

[Your name]

Why it works. A drafted outline turns "would you be interested in collaborating" into a yes or no on something concrete. It also proves you will do your half.

5. Win-back for a lapsed customer

Strictly this is warm email, since they know you. It still behaves like cold outreach because they stopped paying attention months ago.

Subject: [product] since you left

Hi [first name],

You used [product] until [month]. Since then we've [specific
change tied to the likely reason they left, e.g. "added CSV
export"].

If that was the gap, your account is still here: [link]
If it was something else, one line on what was missing would
help me a lot.

[Your name]

Why it works. It names a real change instead of offering a discount by reflex. Even the "something else" replies are useful: they are free churn research.

How to fill the brackets in five minutes

A template saves writing time, not research time. Budget about five minutes per prospect and spend it in this order.

Open their website and read the page closest to your offer: pricing, onboarding, product page or careers. Write the opener from what you see there, in one sentence.

Then pick the proof that matches their situation, not your best-ever result. A smaller, similar customer beats a famous unrelated one.

If five minutes produces nothing specific, skip the prospect. A short list of people you can write to specifically will out-reply a long list you can only write to generically. Picking that list is its own job; AI lead gen tools for small business covers how to build one.

Subject lines that survive the preview pane

The subject only has to earn the open, and it does that by looking like a message from a person. Matched to the templates above:

First touch: "your onboarding emails", "the gap in your checkout flow"
Follow-up: keep the thread; "wrong person?" for the last one
Supplier: "linen tote quote, 500 units", "samples for [spec]"
Partnership: "[their newsletter] x [yours]", "guest issue idea"
Win-back: "[product] since you left", "the export you asked for"

There are forty more, plus the patterns that stopped working, in cold email subject lines that get replies.

Why most cold email now fails

The template is rarely the problem. Most failed cold email either never reaches the inbox or reaches people with no reason to care.

Inbox providers have tightened. Google's sender guidelines ask senders to authenticate with SPF or DKIM and to keep spam rates reported in Postmaster Tools below 0.1 percent, never reaching 0.3 percent. A few complaints from a sloppy list can cross that line.

Generic AI-written outreach makes it worse. When a hundred senders use the same model with the same prompt, the emails look alike, and filters and readers both learn the pattern. The brackets above exist to break that sameness.

Sending is a separate job from writing. Warmed secondary domains, inbox rotation and daily volume caps are what dedicated platforms like Instantly and Smartlead do. Use one if you send more than a few dozen cold emails a day.

Is cold email legal?

In the US, yes, if you follow CAN-SPAM. The FTC's compliance guide says the law makes no exception for business-to-business email: you need an honest subject and sender, a valid postal address and a working opt-out honoured within 10 business days.

The UK and EU are stricter, especially when emailing individuals rather than company addresses. If you sell into Europe, check the local rules before you build a list, not after.

What to automate and what never to

Automate the research and the drafting. Pulling a prospect's recent news, drafting the four parts in your voice and scheduling the follow-ups are tasks software does well and founders do slowly.

Never automate the decision about who gets contacted, or the final read before a first email goes out. One wrong-person email to a big prospect costs more than the hour you saved.

That split is how SoGood's Sales department works: it researches prospects and drafts cold outreach and follow-ups in your brand voice, and you approve who gets contacted. It is not a sending platform, so it does not warm domains or rotate inboxes; pair it with a dedicated sender. SoGood is free to start. Pro is $49 a month with credits included, and extra credits cost $0.04 each.

What to do this week

Pick the one template that matches the email you send most often. Write ten versions for ten real prospects, filling every bracket, and time yourself.

Send them from a warmed address with the follow-ups scheduled for days three, seven and fourteen. Count replies, not opens.

Judge after fifty sends, not ten. If you are below the 3.43 percent benchmark average after four touches, change the list before you change the words. The template can only work on people who have the problem it describes.
