When should the first post-purchase email send?

Customers open order confirmations at a rate no campaign will match, because they are checking that the money left correctly and that the address is right. That makes it the most valuable message in the whole programme, and most stores leave it as the platform default.

Get the essentials right first: what was ordered, what it cost, where it is going, when it should arrive, and how to reach a person if something is wrong. A confirmation that omits the estimated arrival date generates support enquiries within a day.

Then add the small things that reduce anxiety. What happens next, when tracking will appear, how to change an address if they spotted a mistake. Every one of those removes a message to your support team.

Be careful about selling here. A confirmation crowded with recommendations reads as a store more interested in the next order than in this one. One tasteful related item is fine; a full merchandising block is not.

Almost everything worth saying after the confirmation depends on the product having arrived. Setup advice, care instructions, how to get the best from it, an invitation to review: all of these are useless while the parcel is still in transit, and slightly irritating.

So build the flow around the delivery event where your platform can provide it, or around the estimated delivery date where it cannot. That means the same flow behaves correctly for a customer who chose express delivery and one whose parcel took a week.

Between confirmation and delivery, keep to logistics. A dispatch notice with tracking, and an arrival notice if you can detect it, are the messages people want in that window. They are also the ones most likely to be opened, which makes them a reasonable place for a light piece of brand content.

Where delivery data is unavailable, use your own measured transit time rather than the carrier's stated one, and add a day. A review request that arrives before the parcel is the clearest signal a store is not paying attention.

The arrival message should help the customer succeed with the product. How to set it up, what to do first, what mistake people commonly make, where the instructions are. This is the message that reduces returns, and in categories with fitting or assembly it is worth more than any promotional message you could send instead.

The review request comes next, and its timing should reflect how long the product takes to judge. A candle can be reviewed in days. A mattress, a pair of boots or a skincare routine cannot, and asking too early produces thin reviews or none.

After that comes the cross-sell, and it works best when it is genuinely related to what was bought rather than a general catalogue message. Accessories, refills, the companion item: those have a reason to be sent.

The replenishment reminder belongs last and only for consumables, timed to the actual consumption cycle of the product rather than a round number of days. Getting that interval right is often the single most profitable piece of email work a store with consumables can do.

Confirmations, dispatch notices and delivery updates are transactional and are generally sent to everyone, because the customer needs them. Marketing messages depend on consent, and the rules differ by market.

That distinction has practical consequences. A transactional message loaded with promotional content can be treated as marketing, which changes what consent it needs. Keep the selling light in those messages and put the marketing in the ones people opted into.

Deliverability is the other reason to keep them separate. Transactional mail should reach the inbox reliably, and sending it from the same reputation as bulk campaigns exposes it to whatever happens to those campaigns. Many stores use separate sending identities for exactly this reason.

Then suppress correctly. Someone who has just bought should not receive the campaign promoting the product they bought yesterday, and a customer in a returns process should not receive a cross-sell. Both are exclusions that take minutes to build and are usually missing.
