Email Log and Background Sending

Takes email sending out of the page request: messages are queued and sent by a cron command, so checkout and registration load fast. Every notification is logged with its status and can be previewed or resent.

Email Log and Background Sending

In stock CS-Cart an email is sent while the customer waits: the checkout page finishes only after the mail server has answered. On a slow or overloaded mail server that turns the most important page of the store into the slowest one.

What it does

  • Moves email sending into a separate process, so checkout and registration pages load fast.
  • Messages are sent by a cron command at an interval you set — three to five minutes is the usual choice.
  • A log of sent notifications in the administration panel, with the queue and the status of every message.
  • Search through the log and a preview of any message.
  • Manual sending of one or several selected messages.
  • Invalid addresses detected and marked with an «invalid email» status.
  • Configurable log clearing: keep everything, delete successfully sent messages, or delete anything older than a set number of days.
  • A limit on how many messages one cron run sends.

Log clearing settings

Cron settings for the sender

The queue also makes failures visible: a message that did not go out is in the log with its status, instead of disappearing silently as it does by default.

What it covers

Every email the standard CS-Cart functionality sends — to customers, administrators and vendors — including messages generated by third-party add-ons.

Support and updates

The cron command and log settings are covered in the documentation. Six months of free updates, questions through HelpDesk.

FAQ

Will emails be delayed noticeably?

They are sent by the cron interval you set — three to five minutes is typical, which nobody notices, while the pages become fast immediately.

Can I see whether a message was delivered?

The log shows the status of every message, including invalid addresses, and any message can be previewed or resent by hand.

Advantages
One of the biggest benefits is that I can always review emails before they are sent to customers. I can also easily access and review emails that have already been sent. This is especially useful whenever I make changes to email templates or designs, as I can verify exactly how the emails look and behave before they reach customers.

The email queue available under Settings > Queue for Sending Emails provides excellent visibility and control. Installation was very straightforward, and once configured, the cron/queue system handles the sending process automatically while still allowing me to maintain full control over outgoing emails.
Disadvantages
After more than three years of use, I have not found any significant disadvantages.
Comment
I've been using Email Logger by Cart Power for more than three years, and it has become an essential tool for managing customer emails.

I am very satisfied with both the app and the company behind it. Whenever I have had questions, their support has been responsive and helpful. I have also experienced several examples of high-quality custom work from their team.

Overall, I can highly recommend both Email Logger and Cart Power. My experience has been consistently positive, and I would not hesitate to use their products and services again.

Many regards from Switzerland

Installed this add-on to stop email sending from slowing down checkout—and it worked perfectly. Moving emails to a cron/queue made order placement noticeably faster. The email log is super useful (status, preview, resend), and setup is straightforward if you can add a cron job. Highly recommended for any CS-Cart store that wants a smoother, faster customer experience.

Модуль установили решили ряд проблем главная "размещение заказа" долгие зависания вращающегося "колеса" ушли, заказ стал размещаться в течении 1- 3 сек. Это решило отчасти недовольство клиентов. Ряд событий такие как, регистрация пользователя, смена статуса заказа - быстро отрабатываются. Итог в сумме у нас в течении 20 дней на 25 % снизились брошенные корзины, постоянные клиенты сами сказали о ускорении работы на сайте. Данный модуль рекомендуем!! Да, ещё обращайтесь техподдержку компании решается вопросы быстро!!!

Модуль помог решить долгое подтверждение заказа после оформления. К тому же, у кого е-мейл сайта на gmail решает проблему ошибки после включения двухконтактной аутентификации почты

Ранее после оформления заказа или смены статуса отображалась ошибка smtp, обновление статуса можно было прождать минуту, а сейчас все быстро.
Поставили крон 1 раз в минуту и вуаял!

Comment
Модуль работает, как заявлено.

С помощью него решается проблема, когда при оформлении заказов может долго идти загрузка. Из-за этого покупатели начинают перезагружать страницу для повторной отправки заказа, хотя он уже отправлен.

Есть и пара некритичных недостатков:

1) Копится большое число писем на отправку и в этот список попадают даже те письма из событий, уведомления для которых отключены.
Например, при смене статуса на "Обработан" отключена отправка уведомления клиенту и администратору, но письма все равно встают в очередь на отправку и, естественно, не могут отправиться -- нечему отправляться.

2) Перестают отправляться тестовые письма, которые можно отправить, например, из меню редактирования email-шаблонов.

В остальном, результатом работы модуля очень доволен.

Flagship products

Two add-ons that change how a store performs

Everything else we publish improves one screen. These two change the numbers: how customers find products, and how often they come back.

 

Add-on · Search & merchandising

Smart Search

Elasticsearch-powered search for large catalogues. The customer types two letters, sees products with images and prices, and buys from the dropdown — even after a typo or with the wrong keyboard layout.

Visitors who use the search bar are 24% of traffic and 44% of revenue, and convert about 2.5× better than people who only browse categories. If search returns nothing, up to 80% of them leave.
Constructor, Beyond Relevance Report 2025; Google Cloud × The Harris Poll, 2023

Catalogue size Sub-second results on 300,000+ products, Multi-Vendor included
Understands Typos, wrong keyboard layout, synonyms, word forms, SKUs, brands and attributes
Reporting Query analytics — what customers search for and which searches return nothing
Deployment Our cloud, or Elasticsearch on your own server

Add-on · Mobile commerce

PowerApp — mobile app for your store

A native iOS and Android app running on your CS-Cart data: the same products, prices, stock, promotions, reward points and orders. There is no second catalogue to maintain — everything stays in the admin panel you already use.

A mobile site brings a customer in once; an app brings them back for free. Push notifications replace the retargeting budget you spend to buy the same customer a second time.

Platforms Native iOS and Android, published under your own developer account
Home screen Built in the admin panel from six block types, the same way you build website pages
Time to launch Under a week from purchase to submission for App Store and Google Play review
Compatibility CS-Cart and Multi-Vendor 4.18–4.20 · 11 client apps already live in the stores

Services

When no add-on solves it, we do the work

Fixed scope, written specification, a named project manager and a warranty on what we ship.

Custom CS-Cart development

Functionality the platform does not have: add-ons, marketplace mechanics, integrations with 1C, CRM, ERP, payment and delivery providers. We start from a written specification, not from an estimate on a phone call. Details →

CS-Cart upgrade

Move to the current version without losing data, custom code or add-ons. We audit every modification first, upgrade on a staging copy, adapt what breaks and switch over with little or no downtime. Details →

Speed and performance optimisation

Conversion falls by about 4.4% for every extra second of load time. We profile the server, the database and the front-end, then fix what actually costs the seconds — and show you the before-and-after numbers. Details →

Design for CS-Cart

Mobile-first storefront design built on CS-Cart's own template structure, so the layout survives the next platform upgrade instead of becoming a migration problem. Details →

SEO for CS-Cart

A technical audit of indexing, duplicates, redirects, structured data and Core Web Vitals — delivered as a prioritised fix list your developers can act on, or that we implement ourselves. Details →

How we work

What you get besides the code

Before we start

We discuss the goal, offer options and write the specification. You approve scope and price before development begins.

While we build

A named project manager reports progress on a fixed schedule. You always know what is in work and what is next.

Before release

A separate QA pass on every release — the developer who wrote the code is not the person who signs it off.

After handover

Documentation for everything we ship, plus a warranty on the modifications and the project.

Tell us what the store needs to do

Describe the task in a couple of sentences and we will come back with options, a scope and a price. The consultation is free, and we will say plainly if a ready-made add-on already solves it.
