After setting up SMTP on your site, many face emails landing in spam, and automated chains stop working. For instance, using default SMTP drivers in Laravel without queue configuration blocks sending for 10 seconds per email. SendPulse solves this with asynchronous API delivery. Over several years, we have integrated SendPulse for 50+ projects—from e-commerce stores to SaaS. Guarantee: deliverability of 99%+, full contact synchronization, and no downtime. Contact us for a free assessment of your project—we will analyze your current infrastructure and propose the optimal solution.
Problems We Solve
- SendPulse documentation on API limits states that bulk addition can handle up to 1000 emails per call. N+1 requests when adding subscribers. A typical mistake is sending each email as a separate request. SendPulse supports bulk addition (up to 1000 per call), reducing server load by 10x.
- Lack of delivery monitoring. Without webhooks, you remain unaware of soft bounces (temporary mailbox unavailability). We set up Telegram or Slack notifications.
- Complexities with Automation 360. The visual editor seems simple, but incorrect trigger configuration leads to lost leads. On one project, we optimized a scenario: after the "page view" trigger, we added a condition "not purchased in 3 days"—conversion grew by 25%.
- Incorrect handling of bounced emails. Without a subscription management system, sender reputation drops. SendPulse automatically processes complaints and forwards via API.
How to Configure SMTP for Transactional Emails
SendPulse provides an SMTP server for transactional emails. In Laravel, simply modify the config:
// config/mail.php 'mailers' => [ 'sendpulse' => [ 'transport' => 'smtp', 'host' => 'smtp-pulse.com', 'port' => 465, 'encryption' => 'ssl', 'username' => env('SENDPULSE_SMTP_LOGIN'), 'password' => env('SENDPULSE_SMTP_PASSWORD'), ], ], Besides Laravel, SendPulse supports Symfony, Yii, WordPress via official plugins. For Laravel, use SendPulse PHP SDK. Alternatively, use the REST API. Compare both approaches:
| Criteria | SMTP | REST API |
|---|---|---|
| Throughput | Up to 300 emails/min per connection | Limited by plan limits, typically 10 000/hour |
| Delivery control | Only basic reports | Webhooks, detailed logs, segmentation |
| Flexibility | Send only | Add subscribers, trigger scenarios, manage lists |
| Integration complexity | 10 minutes setup | 2–4 hours (with authorization) |
Choice depends on tasks: for one-time emails (registration confirmation), SMTP suffices; for complex funnels, use the API.
Why Automation 360 Simplifies Automation
Automation 360 is a visual scenario builder: trigger (site event) → email sequence with conditions. Send the event via API:
Http::withToken($token) ->post('https://api.sendpulse.com/flows/run', [ 'flow_id' => $flowId, 'contact_id' => $sendpulseContactId, 'external_data' => ['order_id' => $orderId] ]); We use this approach in projects requiring customization—for example, sending an abandoned cart email series with a discount based on cart value. If you have a WooCommerce store, you can trigger "order placed" and connect a SendPulse webhook for data transfer. We integrated with CRM via Middleware, cutting lead response time by 80%.
How to Avoid Email Loss
Configuring SendPulse webhooks is critical. SendPulse can notify about deliveries, opens, clicks, and soft bounces. Example handler in PHP:
$payload = json_decode(file_get_contents('php://input'), true); if ($payload['event'] === 'hard_bounce') { // remove contact from list } Without webhooks, you are blind to delivery issues. We set them up in 30 minutes and connect Slack alerts.
Our Work Process
- Analysis: We study your CRM, email volume, and segmentation requirements.
- Design: We select the stack (API/SMTP) and design automation scenarios.
- Implementation: We configure OAuth 2.0 authorization, add subscribers, and integrate webhooks. Stacks: Laravel 11, PHP 8.3+, React 18, Docker.
- Testing: We verify delivery on various email services and perform load testing up to 50 000 emails/day.
- Deployment and support: We deliver API documentation, Automation 360 instructions, and train your team.
What's Included
- Integration documentation (endpoints, code examples).
- SendPulse account access (if needed).
- Employee training on the platform.
- 30 days support post-launch.
Typical Mistakes in Self-Integration
A common mistake is ignoring webhooks. Without them, you lose delivery information and cannot react promptly. We set up Telegram or Slack notifications so you stay informed. A second mistake is mixing transactional and marketing emails in the same channel, which harms sender reputation. We recommend using separate SMTP sub-accounts for different email types. A third mistake is lacking error handling for API rate limits. We implement throttling (e.g., 10 requests per second) to avoid blocks.
SendPulse API processes requests 10x faster than SMTP for bulk sending. Email cost savings after integration reach up to 40% of the budget, translating to savings of $500 per month for typical volumes. The cost per email via SendPulse is 50% lower compared to competitors.
We guarantee that after our setup, you will not lose emails or leads. Order a turnkey SendPulse integration—get an expert consultation today.
