Rechner runs email, SMS and WhatsApp campaigns that reach customers directly—no algorithm deciding who sees it, no bid to win before it is delivered.
Segmented properly, written for each channel, and measured against what it actually returns.
Owned vs rented
Every follower you have was acquired on a platform that decides how many of them see your next post, and charges you when it decides fewer should. That reach can be reduced overnight by a change you had no part in.
A customer who gave you their email address or opted into WhatsApp updates can be reached directly, repeatedly, at almost no marginal cost. For most businesses, it is the highest-return channel they under-use.
Why direct channels perform
Common situations
Almost always a targeting or relevance problem rather than a volume problem.
Years of collected customer contacts sitting in a spreadsheet because no one was sure what to send or whether they still could.
One blast to the entire database regardless of what people bought, when they last engaged, or whether it is remotely relevant.
Sends land in promotions or spam, or arrive so frequently and so generically that subscribers stopped opening months ago.
Customer conversations run from a staff member’s handset with no templates, no records and no continuity when they leave.
Someone enquires, receives one reply, and then never hears from you again unless they chase it themselves.
Real concern about consent, opt-in requirements and WhatsApp’s business policies stopping campaigns from running at all.
What we do
The mistake is treating them as interchangeable. The message decides the channel, not the other way around.
Newsletters, promotions and lifecycle sequences—designed, written and automated, with deliverability and mobile rendering handled properly.
Short, time-sensitive messages for reminders, flash promotions, service alerts and confirmations where near-immediate attention matters.
Broadcast setup, approved message templates, opt-in flows and conversational follow-up on the channel most Malaysians actually check.
Dividing contacts by purchase history, behaviour, lifecycle stage, language or interest so each send has a reason to be relevant.
Testing subject lines, send times, offers and formats, then applying what wins to the following campaign.
Delivery, open, click and conversion reporting per segment, so you can see which audiences justify continued sending.
How we work
Each campaign should teach you something that makes the following one perform better.
Clean and organise the list, then divide it so messages are relevant to each group rather than generic to all of them.
Build each campaign for its channel—email templates, SMS copy within character limits, WhatsApp templates that meet policy requirements.
Schedule for when each audience actually engages, with testing on subject lines and timing where volume allows.
Report delivery, opens, clicks and conversions by segment, and use the result to refine the next send.
A worked example
Most businesses lose more revenue to unfollowed-up enquiries than to campaigns that underperformed. A sequence handles the follow-up nobody has time for.
What you get
Acquiring a new customer costs considerably more than getting an existing one to return. Direct channels are where that gap is closed.
Timely, relevant contact keeps you present with people who have already bought, which is where margin is easiest to find.
Reaching your existing list costs a fraction of acquiring equivalent attention through paid advertising.
SMS and WhatsApp are typically read within minutes, which suits reminders, confirmations and time-limited offers.
Automated sequences handle the persistence that manual follow-up loses to a busy week.
Direct channels are among the easiest to measure end to end, from delivery through to the resulting purchase.
Consent capture, opt-out handling and approved templates configured so campaigns can run without policy risk.
Longer content, images, multiple links and anything the reader may want to return to later. Lowest cost, most tolerant of frequency.
Very high open rates within minutes. Best reserved for genuinely time-sensitive messages—reminders, alerts, closing offers.
Direct, personal and expected to allow a reply. Strong in Malaysia, but governed by template approval and opt-in rules.
Direct channels are permission-based. Over-send and you do not just lose attention—you lose the contact permanently.
Why Rechner
Website forms, landing pages and lead magnets that grow the list are part of our web work, so acquisition and messaging connect.
Email design, imagery and copy produced by the same team, rather than assembled from a generic template library.
Our workflow automation practice means sequences can connect properly to your CRM, website and internal systems.
Campaigns written in English, Bahasa Malaysia and Chinese, segmented by language preference rather than sent to everyone in one.
We will push back on send frequency that risks the list. A database burned out for one quarter’s targets is expensive to rebuild.
Technology & architecture
Campaigns run through established email platforms, SMS gateways and the WhatsApp Business API, connected to your CRM or website where automation is required.
Deliverability work—domain authentication, sender reputation, list hygiene and opt-out handling—is set up before volume sending begins, because a message that lands in spam was never a campaign at all.
Delivered, then opened, then acted on. Each step depends on the one before it.
Consent & compliance
WhatsApp Business requires opt-in and approved templates for broadcast messaging. Email requires a clear consent basis and a working unsubscribe. We set up capture, records and opt-out handling properly, because the alternative risks the channel itself, not only a single campaign.
Clear opt-in. Honest expectations. Easy opt-out. Records kept.
List quality
Sending to contacts who never open damages sender reputation and pushes future messages towards spam folders—including for the people who would have read them. Regular cleaning protects the deliverability of the whole list.
With whatever list you already have, however neglected. Cleaning, segmenting and sending one genuinely relevant campaign usually reveals more than any strategy document.
After that, automated sequences—welcome, follow-up, post-purchase—tend to deliver the best return, because they run continuously without needing a campaign each time.
Before the first send we check
Email suits detailed, visual campaigns and costs the least per contact. SMS gets near-immediate attention and is best kept for time-sensitive messages. WhatsApp works well for direct, conversational updates and is widely used in Malaysia. We help decide which channel—or mix—fits each message.
Yes. We set up and manage WhatsApp Business broadcast messaging, including customer opt-in flows and message templates that comply with WhatsApp’s business messaging policies.
Yes. Direct channels are permission-based—WhatsApp broadcast requires opt-in and approved templates, and email requires a clear consent basis with a working unsubscribe. We set up consent capture and opt-out handling as part of the work.
Yes. We segment by behaviour, purchase history, lifecycle stage, language or interest, so campaigns land as relevant messages rather than generic blasts.
It depends on your category and what you have to say. Over-sending is the most common cause of list decay—we would rather send less frequently with a genuine reason than exhaust a list for one quarter’s numbers.
Usually a combination of missing domain authentication, poor sender reputation, stale contacts who never open, or content patterns that trigger filters. We address deliverability setup and list hygiene before increasing send volume.
Yes. We produce campaigns in English, Bahasa Malaysia and Chinese, and segment the list by language preference so each contact receives the version they actually read.
Usually yes, depending on the platforms involved and the integrations they support. Our automation experience means sequences can be connected to your CRM, website forms and internal systems.
We track delivery, open, click-through and conversion rates across email, SMS and WhatsApp, reported by segment so you can see which audiences and messages are actually driving revenue.
It depends on how the contacts were collected and how long ago. Sending to a very stale list can damage deliverability for everyone on it, so we usually recommend a careful re-engagement approach rather than a full blast.
