Using ReMail to resend a campaign to non-engaging subscribers


Even when you've got an email into your contacts' inboxes, it can be the case that they just don't get round to reading it. That's where our ReMail tool comes in handy.

ReMail enables you to automatically resend a campaign with a new subject line to anyone who isn't tracked as opening it after a set number of days. This gives you a second chance to grab their attention.

Please note: ReMails are considered separate campaigns for the purposes of reporting and billing.

Setting up a campaign ReMail

When scheduling a campaign send, the third step on the 'Select contacts and schedule campaign' screen will ask whether you want to send a ReMail.


On selecting Yes, you'll be asked to set:

  • number of days after the immediate/scheduled send that the ReMail should be sent to non-openers. This can be any number of days between 1 and 30.
  • the subject line that should be used. By default, we'll reuse the subject line from your campaign (or in the case of a split test campaign, the subject line of the winning version). You might want to change the subject line though to try a new message, given that the first one didn't generate an open, or in order to add urgency and immediacy to your campaign (e.g. "Offer ends today").


Dynamic subject lines can't be changed

Changing the subject line isn't available for campaigns using dynamic subject lines. The same dynamic subject lines will be used in the ReMail of the campaign and can't be changed. 

If you want to be able to change the subject line of the ReMail, you'll need to ensure you're using a static subject line instead in the 'Create' step.

Once your campaign is sent to the outbox, your ReMail is scheduled and will go out automatically to any contact for whom an open hasn't been tracked.

A tracked open results from:

  • opening an email (and downloading the images) for the HTML version of the email
  • following a link in the HTML or plain text version of the email

Reports for ReMail campaigns

Once your ReMail campaign has been sent, it will have a report just like all of your other campaigns.

You'll also be able to access it by selecting ReMail report via the campaign overview report for the original campaign.


Editing or cancelling your ReMail campaign

To edit or cancel your ReMail campaign, find the ReMail settings in Reporting > Campaign reports > (select your original campaign). Here you'll see the resend date and the new subject line of your ReMail. You can edit these by changing the Send on or Subject line boxes and selecting the green tick
If you want to cancel your ReMail entirely, select Cancel Remail. You'll see a warning that if you do cancel, you won't be able to get the ReMail back or create another one. If you're sure, select Cancel ReMail again. If you've changed your mind, select Keep ReMail to make no changes. 


Set up ReMail to resend to non-openers

There are two options to setup ReMail after the send.

  • Create a segment to identify the non-openers of the campaign, and then send a copy of the campaign to that segment
  • Go to the campaign's report, select More reports > Non-openers, select Export > Create address book and then send a copy of the campaign to all of the non-openers in that address book.

    Glad you like it, guys! Let us know if you get any good case studies of using it.

    Is is possible to only send the remail to a portion of non-openers, to be able to test it, rather than sending to ALL non-openers?

    Hi Tracy,

    It's not possible to send only to a portion of non-openers at present, though might be worth a feature request; but if you wanted to try this tactic out one option would be to get the data from the non-openers and send them a copy of the previous campaign - that way you can judge the kind of response rate you get second time round (with a new subject line).

    Can you see a report merging the data from the original and re-mailed campaign?

    I know you can look at headlines in the compare function, but we need to see a single report for the campaign as a whole.

    Hi Mark,

    We don't have a combined campaign+ReMail report available at present; definitely worth a  feature request.

    We do, however, have in the pipeline the ability to produce better reports across groups of campaigns using the segmentation tool (currently available to dotMailer test pilots).

    I would like to remail those who didn't open first time round.  I didn't set up the remail at the time of the first e-shot. Is it possible to set it up retrospectively?

  • Avatar

    On my report overview screen, it says "Failed to send remail" even though I had set it up. Any reasons as to what I did wrong? And do I assume no re-sends were done?  Do I have to manually send the remail or is there a way of sending to the non-openers only? thanks for any help provided.

    Hi all,

    @Rowland — I'm afraid there isn't a way, at present, to set up a retrospective ReMail. You can, however, create an address book of non-openers from the non-openers report which might speed things up a little.


    @Moses — I just had a quick look and it seems like you did set up everything right, however your account is currently set up to only send 500 emails a month; that ReMail would have pushed it over your maximum allowed to 622. Sorry the error message isn't any more informative at the moment. Once your account is fully activated for unlimited sends, you won't see this problem.

    Best wishes,

    Hi guys,

    Just been looking at the  Remail functionality and realise it only addresses to non-openers.  We want to aim at 'non-repliers' , who may have read the first email but put off replying until a bit later and for whom a reminder would be useful.

    In the past, we just resent to everyone and thought Remailer would be a better tool, but evidence on attendees at events suggests we're missing some.

    Any suggestions?

    I have a question about  the "Edit ReMail" function. Is this for editing the actual email or is it only to edit the ReMail date and/or criteria.

    Thank you.

    Hi Karin,

    The 'Edit ReMail' function can be used to alter the ReMail send date and to change the ReMail subject line. You can't edit the content of the ReMail campaign, although you can change the following settings for any sent campaign as outlined in this article - Editing a sent campaign's settings

    Hope this helps.

    We have found that when we are running a campaign (particualrly a short term campaign) a remail on the same day works well.

    For example, we send an email at 8.30am reminding customers our offer ends at midnight. We then send a remail of this at 8pm and the response is quite good.

    To date, i have been doing this manually, is there are a way to do this automatically? At the moment you can only select to send the remail a number of days after original send rather than hours or days.

    Hi Jemima,

    You can't set a <24 hour ReMail in the usual way with the current tech, but one way to do it is to use the dotmailer program builder. This will give you even greater control over setting up even a three (or more) stage ReMail.

    Below is an image showing how you could do a simple ReMail using the program builder.

    If the campaign was setup on monday with remail setting is 2 days for non opener, then the campaign sent to A on monday and sent to B on tuesday.

    Will it send remail to A on wednesday and remail to B on thursday? Or the remail schedule is fixed when the campaign was setup (wednesday)?

  • Avatar


    Yes, the ReMail schedule is indeed fixed from the day the campaign was sent out. So, in the scenario you outline, both A and B will be sent the ReMail campaign on the Wednesday, as that's two days after the campaign was originally sent. Even though A and B may have received the original campaign on different days, the ReMail send will not become staggered as a result of this.
