    9 Bump Email Templates and When to Send Each

    Nine bump email templates for threads where the other side owes you something, the three checks that make a bump correspondence, and what never to send.

    Three checks that decide whether a bump is correspondence. A thread that fails any of them is a cold thread, and a cold thread gets no bump.

    The short answer

    A bump email is a one or two line reply on an existing thread that brings an unanswered message back up. Send one only where a thread exists, the person replied or agreed to something, and they owe something specific. Name what is owed, add one new thing, send it once, and never bump a cold prospect.

    Key takeaways

    • Three checks decide whether a bump is correspondence: a thread already exists, the person replied or agreed to something, and they owe something specific; a thread that fails any of them gets no bump.
    • We do not send the cold bump, because our campaigns carry one message with no thread replies to people who did not answer, and a later approach is a new campaign on a new premise.
    • Every bump carries one new thing, such as a pointer to the part that matters, a dependency, a real date or a forced-choice question, because a bump with nothing new is only impatience.
    • A bump inherits its thread's subject and is sent once; if it draws nothing, the next message changes job to a real deadline or a close-the-loop note, and then you stop.

    Reviewed and updated September 18, 2026

    A bump is the shortest email in business: one or two lines, sent on an existing thread, to bring an unanswered message back to the top of an inbox. Whether it reads as diligence or as nagging depends on one thing the wording cannot fix, which is whether the other person owes you anything.

    This page carries nine bump templates, and all nine are for threads where the other side does owe something: a reply they promised, a decision with a date, a deliverable, an answer to something they asked for. It carries none for the case most bump advice is written about, the cold prospect who never replied, and the first section says why. Every template below is invented for illustration, and none carries a reply rate or a results claim.

    Where we differ from standard practice

    The market teaches the bump as a step in a cold sequence. Mailchimp's guide to the email bump, as fetched on 18 September 2026, defines it broadly, "An email bump is a short follow-up message sent to prompt a reply to an unanswered email.", and describes a convention for repeating it: "Many professionals rely on the Rule of 3: a simple, effective structure for sending up to 3 bump emails, each slightly different in tone and content." That is industry practice, and it is reported here as such.

    We do not send the cold bump. Our campaigns carry one message, with no bumps and no thread replies to people who did not answer. The argument and our own published figures are in why we stopped using follow-ups, and the market's numbers are read against their cost in cold email follow-up benchmarks. The working test is in meeting reminder emails, which names bumps as the messages we do not send: if a message would still make sense when the answer is already yes, it is correspondence, and if it only makes sense as another attempt to get a yes, it is a bump in the bad sense. Our guide to cold emailing product managers adds the reader's view, which is that a pure bump reads as evidence the sender has nothing else to say.

    Omnisend's guide, published on 11 May 2026 and fetched on 18 September 2026, defines the bump more narrowly than Mailchimp does, and its definition contains the condition that matters: "A bump email is a short message you can send on an already existing thread to remind the recipient about the conversation you had and bring the thread back to the top of their inbox." A conversation you had. Flodesk's five bump templates, last modified on 3 August 2026 and fetched the same day, include an overdue invoice and a job application, which are both cases where a relationship already exists. Read that way, the bump is a tool for live threads. Everything below keeps it there.

    Three checks: a thread exists, they replied or agreed, they owe something Check one A thread already exists No: stop Check two They replied or agreed No: stop Check three They owe something No: stop The bump is correspondence Send it once, on their thread Any stop: a cold thread No bump. A new campaign, later.
    Three checks that decide whether a bump is correspondence. A thread that fails any of them is a cold thread, and a cold thread gets no bump.

    The merge fields, explained once

    {{first_name}} is the recipient. {{thing}} is what is owed or was sent, named the way they named it. {{date}} is a real date: when it was sent, when it is due, or when you will act. {{your_name}} closes every template. A bump has no greeting line beyond the name and no sign-off beyond yours, and every template is sent as a reply on the existing thread unless its subject says otherwise.

    Section 1: They asked, you delivered, they went quiet

    Template 1: They asked you to send something

    Subject: Re: {{their_subject}}
    
    {{first_name}}, the {{thing}} you asked for went over on {{date}}. The part that answers your question about {{their_question}} is on page two.
    
    Is it what you needed, or should we cut it differently?
    
    {{your_name}}
    

    Why each line is there. {{their_subject}} is the subject of their request and {{their_question}} is the question they asked. The first sentence restates that they asked, which is what makes this correspondence. It then adds the one new thing, a pointer to the part that matters, so the bump is worth opening even if the first message was read. The closing question offers two answers, and both are easy.

    Template 2: A proposal they requested

    Subject: Re: {{their_subject}}
    
    {{first_name}}, on the proposal you asked for: is it the scope or the timing that needs another look? One word back and we will rework that part by {{date}}.
    
    {{your_name}}
    

    Why each line is there. The fuller follow-ups after a proposal are Templates 3 and 4 in our proposal email templates page. This is the bump version: no recap, no added material. It asks a forced-choice question, because a stalled proposal may be stalled on one thing, and naming two candidates is easier to answer than an open question. The promise with a date shows what their one word buys.

    Section 2: After a meeting, with actions on their side

    Template 3: Actions they own

    Subject: Re: {{meeting_subject}}
    
    {{first_name}}, after our call you were going to {{their_action}}. We have held {{your_action}} until it arrives, so nothing moves on our side until then.
    
    Still on for this week?
    
    {{your_name}}
    

    Why each line is there. {{meeting_subject}} is the subject of the meeting thread, {{their_action}} is what they said they would do, in their words, and {{your_action}} is what you are holding. The bump names their commitment without blame and states the dependency, which is the new information: your work is waiting on theirs. The question asks about a time, which is kinder than asking whether they did it.

    Template 4: The date they named has come

    Subject: Re: {{their_subject}}
    
    {{first_name}}, you asked us to come back in {{their_month}}, so here we are. Is this still worth a conversation, or has it moved?
    
    {{your_name}}
    

    Why each line is there. {{their_month}} is the month they named. They set this date. The bump quotes their request back, claims nothing about their situation and offers an exit in the same breath. If it draws nothing, the next and last message closes the loop, and the wording for that is in the cadence section.

    Section 3: Inside your own company

    Template 5: The internal bump to a colleague or the closer

    Subject: Re: {{internal_subject}}
    
    {{first_name}}, we need {{thing}} from you to reply to {{customer}} by {{date}}. If you cannot get to it, tell us who can and we will ask them.
    
    {{your_name}}
    

    Why each line is there. {{internal_subject}} is the subject of the internal thread and {{customer}} is the account that is waiting. The internal bump fails when it says only any update. This one states what is needed, for whom, by when, and gives the colleague a way out that still moves the work. It never copies their manager. An escalation is a different message, and a bump disguised as one poisons the next request.

    Template 6: Forwarding the thread to a new stakeholder

    Subject: Fwd: {{their_subject}} (context for {{new_name}})
    
    {{new_name}}, {{first_name}} suggested we bring you in. The short version of the thread below: {{one_line_summary}}.
    
    The open question is {{open_question}}. Are you the right person for it?
    
    {{your_name}}
    

    Why each line is there. {{new_name}} is the new stakeholder, {{one_line_summary}} is the thread in one sentence and {{open_question}} is the one thing still undecided. This is the only template here that changes the subject, because the reader is new and must not have to read the whole thread to see why they are on it. It names who suggested them, which is the licence to write. The emails for working several stakeholders inside one deal are a larger subject, and this page carries only this one.

    Section 4: Customers, partners and vendors

    Template 7: A customer who owes a renewal decision

    Subject: Re: {{renewal_subject}}
    
    {{first_name}}, your term ends on {{date}}, and we need your decision by {{decision_date}} to keep the current terms in place. Renew as is, change something, or stop?
    
    {{your_name}}
    

    Why each line is there. {{renewal_subject}} is the subject of the renewal thread and {{decision_date}} is the last day you can act on their answer. There is a contract, so there is an expectation of contact. The bump states the two dates and lists the three possible answers, including stop, because offering stop in one word makes renew just as easy to say.

    Template 8: A partner on a deliverable

    Subject: Re: {{project_subject}}
    
    {{first_name}}, the {{thing}} was due from your side on {{date}}, and our launch date depends on it. What is a realistic date now? We would sooner move the plan once than guess.
    
    {{your_name}}
    

    Why each line is there. {{project_subject}} is the subject of the project thread. Partners slip for ordinary reasons, and a bump that asks where is it invites an excuse. Asking for a realistic date invites a plan. The last sentence says what you will do with their answer.

    Template 9: A vendor you are buying from

    Subject: Re: {{quote_subject}}
    
    {{first_name}}, we asked for {{thing}} on {{date}} and need it to take this to our approver on {{decision_date}}. Can you get it to us before then?
    
    {{your_name}}
    

    Why each line is there. {{quote_subject}} is the subject of your request. Buyers bump too, and a seller should know what a good one looks like from the other side. It names the ask, the internal date it serves and nothing else.

    Subject lines: inherit the thread, and when to change it

    A bump inherits its subject. The thread's subject is the record of what was asked, and replying under it keeps that record attached. So this section is mostly about the exceptions.

    Keep the subject unchanged (the default). The rule: if they wrote or replied on this thread, its subject is theirs, and yours rides it.

    • Re: Rollout plan for the Leeds depot
    • Re: Proposal for the March start
    • Re: Notes and actions from Tuesday
    • Re: Renewal, term ending 30 June

    Change it when the reader is new. The rule: say whose thread it is and why they are on it.

    • Fwd: Rollout plan (context for {{new_name}})
    • Fwd: Security review, one open question for you

    Change it when the thread subject has become wrong. The rule: keep their words and append the current question, so the history still matches.

    • Re: Rollout plan, now the weekend cover question
    • Re: Proposal for the March start, April dates attached

    Internal threads. The rule: lead with the customer and the date, because colleagues triage by who is waiting.

    • Re: {{customer}} reply due Thursday
    • Re: Quote for {{customer}}, need pricing sign-off by the 12th

    Never. Re: on a message that is not a reply. It is the fake thread, and the reader finds out in one click.

    The cadence: once, then what

    A bump is sent once. If it draws nothing, a second bump is the same message with less dignity, so the next message changes job. It either carries a real deadline, as in the renewal template, or it closes the loop: say you will stop asking, say what happens on your side as a result, and leave one door open. The close-the-loop note in the no-show email template is a model for the tone. After that, stop. If the account matters and something new becomes true of it later, that is a new message on a new premise.

    Timing follows the thing that is owed. Bump when the date in the agreement arrives, or when your own work is actually blocked. No interval is given here, because no data exists on bump timing in live threads.

    1. When the date in the agreement arrivesThe bump

      Once, on their thread, carrying one new thing.

    2. If it draws nothingA message with a different job

      A real deadline, or the close-the-loop note.

    3. After thatStop

      Later, something new is a new message on a new premise.

    The cadence of a bump inside a live thread: one bump, one closing message, then nothing.

    What not to send

    Any bump on a cold thread. If they never replied, there is no thread, only your messages. The three checks above all fail, and the pages linked in the first section explain the cost.

    The fake Re:. A subject dressed as a reply to a conversation that never happened. It gets the open and loses the reader in the same second.

    Bumping this to the top of your inbox, to a stranger. The phrase announces that the only new information is your impatience. Inside a live thread it is merely empty. To a stranger it is the definition of the thing we do not send.

    The guilt bump. A line such as we have tried you a few times, or any count of your own attempts. It puts the reader in the wrong, and people who feel caught stay quiet.

    The bump with nothing new. Any thoughts, or just checking in. Every template above carries one new thing: a pointer, a dependency, a date or a forced choice. If you have nothing new, you have no bump yet.

    The short version

    Bump only where a thread exists, the person replied or agreed to something, and they owe something specific. Send it once, as a reply under their subject, in two or three lines that name what is owed and add one new thing. If it draws nothing, send one message with a different job, a real deadline or a close-the-loop, and then stop. To people who never replied, send nothing. Where a cadence is the right tool at all, such as warm inbound and existing customers, is set out in our page on the sales cadence.

    Questions

    Frequently asked questions.

    Frequently asked questions
    What is a bump email?
    A bump email is a short reply, usually one or two lines, sent on an existing thread to bring an unanswered message back to the top of the recipient's inbox. Omnisend's guide defines it as a message on an already existing thread that reminds the recipient about a conversation you had. It works as correspondence when the other person owes something, such as a decision or a deliverable.
    How do you politely bump an email?
    Reply under the original subject, use the person's name, and in two or three lines say what is owed and add one new thing: a pointer to the part of your document that answers their question, the work you are holding until their action arrives, or a real date. End with a question that has an easy answer. Leave out apologies, counts of earlier attempts and the phrase just checking in.
    Should you bump a cold email that got no reply?
    We do not. Our campaigns send one message, with no bumps and no thread replies to people who did not answer, because each later touch goes only to people who saw a message and chose not to respond. If something new becomes true of the account later, it gets a new campaign on a new premise, sent as an opening message with its own subject line.
    How many times should you bump an email?
    Once. Published guides describe sending up to three bumps, each slightly different in tone, but inside a live thread a second bump is the same message with less dignity. If the first draws nothing, change the job of the next message: give a real deadline, or close the loop by saying you will stop asking and what happens on your side as a result. Then stop.
